Weird timing in chart

Hello

I am currently taking data of a CDAQ card (which I am simulating). It's an RTD, so I take the brute strength and put it into an equation to get the actual values of temp. I don't know if that's right, right now, but this isn't a big problem.

The problem is I'm trying to add several diagrams together so that I can display multiple RTD temperature simultaneously. I have a chart showing the output data, but when I put in the chart with the same data twice, something get messed up.

I'm querying data 100 times per second, so I have a scale factor in the chart in multiples of 0.01, and I have the lag in absolute time. When I run the VI I can see the timescale on the maps are not equal. I think that the multiple chart runs about 2 times faster. I don't know exactly where I went wrong here, but I feel there is a better way to do what I do.

Any help would be great.

Thank you.

If your goal is to have two of the same plot on the second chart, you can pass the waveform data in a node to build array as both two inputs. Then you can wire the table in the table of waveform.

See here for descriptions of the different styles of painting and graphics:http://zone.ni.com/reference/en-XX/help/371361H-01/lvconcepts/types_of_graphs_and_charts/

There are several ways to update each different kind of chart.

I'm not quite sure what your goal is here however. Both parcels will be directly above the other and indistinguishable.

  • blocked server and then weird spike in chart

    I had a few (4) virtual machines in one of them, I installed oracle (free version) and in the middle of the installation, my connection vic lost response to the server. All virtual machines where works well and I was still able to load websites that fast when zippy hosted virtual machines on the box. Ping response was very well to all the IP addresses to the virtual machines as well as the ip address of management that I had the slow response time. A few minutes later, I got a nmap (sniffed ports) and I noticed almost all TCP/IP ports when closed. Onlys 2 or three where open. SSH was not one of them.

I was doing a lot of i/o with oracle who settle then vmware stall might not have enough resources to juggle a demanding IO vm?

    It is a Windows service, so you would need to access (for example, RDP or Citrix) the vCenter server runs on.

  • calendar of the graph

    Hello, I have a problem with timing waveform Chart, don't know exactly if this problem had been resolved already, but here goes:

    I have a chart in waveform showing sending analog output port voltage GI, so do a few tests, I put a signal generator and then I put the signal to the square wave with frq = 1 to see if the signal changes once per second, as it normally would. Yes, well he changes and seem to be ok, but the weather turns (about ofc) 10 times faster than it does in reality. only when I stop the vi, I see that the signal with a frequency of 1 Hz square is a TRUE 1 Hz. but is there a way to show the time it actually happens? and so that the graph would not move as it is having an epileptic seizure, but as a NORMAL move graphic hope my description is sufficient, if you have any questions, do not hesitate to ask thank you!

    You should be aware that a graph, by itself, has no timetable except for the default value of 1 second between samples. You must provide any other time by using a type of waveform or by specifying the dt by writing to the property of multiplier.

  • Item in the list of the spark 0 not visible

    Strange.  DataProvider contains an element to zero, but it seems not visible in the list.  Select the item that works very well and the data is there... it's just not visible.  Is this a known bug?  It happens with or without the custom skinClass.

    Any ideas?

    Don

    < s:List id = "topLeft" creationComplete = "topLeft_creationCompleteHandler (event)" dataProvider = "{photosDP}" borderColor = "0xffffff" borderAlpha = "0.3" skinClass = "TouchListHorizontal" width = "100%" height = "100%" itemRenderer = horizontalCenter 'ImageRendererPhotosThumb' = '0' red '0' = > "
    < s:layout >
    < s:HorizontalLayout horizontalAlign = "center" verticalAlign = "middle" / >
    < / s:layout >
    < / s:List >

    Try to give the Image an explicit width/height.

    Or instead of using mx:Image, try using a s:Label and show the URL in the form of text. See if the first element is visible in this case. There is perhaps a weird timing with auto mx:Image problem controls in a sizing element converter.

  • Weird problem with control of the ring and foot

    So I have some sort of weird issue with a control of the ring and a chart. I'm with LabWindows/CVI on a Windows 7 computer. The part of the program I'm looking at is basically to navigate through data - there are several "transition" (rehearsals experience), and you can choose the one that you want to watch in the list.

    Normally, you would select transitional in the list, it plots the data, then it is done, basically. However, all of a sudden (don't know how long it spent for), when I select anything except 'Average', he made all the tracing and such, then it changes control of the ring to 'Average' (it is not plot the average data or generate all the reminders that I can tell).

    Now the thing the more bizarre as you can see below, it seems that the switch happens just when I draw something on the chart:

     

    So, it's just weird. The code in this section is here:

       if(uidc.polyon) {
                polynomial_subtraction(curr_data, np, uidc.polyord, 0); // 0 Skip for now
            }
    
            // Scale the curr_data for gains, then pre-scale the FFT data
            // to have no change in the power spectrum (multiply by (2/np)
            for(j = 0; j < np; j++) {
                fft_data[j] = curr_data[j]*2/np;
                curr_data[j] = curr_data[j]*uidc.fgain[i] + uidc.foff[i];
            }
    
            uidc.fplotids[i] = PlotY(dc.fid, dc.fgraph, curr_data, np, VAL_DOUBLE, VAL_THIN_LINE, VAL_NO_POINT, VAL_SOLID, 1, uidc.fchans[i]?uidc.fcol[i]:VAL_TRANSPARENT);
    
            // Prepare the data.
            FFTEx(fft_data, np, npfft, NULL, FALSE, curr_fft);  // Do the fourier transform
    

    DC is a structure that I use to better organize some UI controls and uidc is for display RAM variables, then dc.fid is the Panel that is embedded in the tab "FID", dc.fgraph = FID_Graph and corresponds to the chart control. Control of the ring is actually in a child Panel, dc.cloc [0]. FID_Graph has a point, it can produce, but the reminder is empty (no not coded something there yet).

    I have also considered that perhaps something in another thread (I don't think there is, but whatever) I see is the cause, however, this behavior still happens on that line. I tried to break in different locations, on hold, then continues, as well by adding a loop containing Delay (0.01), a loop of 100 times. Always happens after the conspiracy.

    Does anyone have any idea why this might be happening?

    Hi Paul,.

    I don't have a solution, but I wanted to point out that, even if you see the ring to change its value only when you call the function of tracing, that doesn't say what this function call that really changes the value of the ring. In CVI, some drawing operations are batched, for performance reasons, and the Panel updates only visually at certain times. One of those moments when you draw a chart data. Yes, the ring changes visually at this time there, but it is probably just 'catch up' a change earlier.

    As you are looking through the code, when the value of the ring, you can use the term > command update UI to force the update panel, so that you don't have to wait for the tracing function and see if all goes well this change happening earlier.

  • How to put 2 different forms of wave with the timestamp on a chart

    Hello

    I'm putting the 2 waveforms with different stamps on the same chart.

    I'm able to do that if I post my data in my chart once.

    When I write to my chart several times, the new data replaces old data, instead of concatenation to the old data.

    See the vi attached for what I'm trying to do.

    Can anyone suggest how to do this correctly?

    Thank you.

    -Matt

    It works.  It's your data.  Put a longer wait statement in the loop and watch.

    You create 1/10 seconds of data in each simulated waveform.  You have a millisecond 33 wait between your 2 simulations.  The loop For will run super fast with only this 33 msec waiting that is less than 1/10th of a second.  Then of course some data will overwrite old data.

    Change your Simulations for "Simulate Acquisition Timing" rather than "Run as fast as Possible" which will slow down the loop and make it more realistic timetable.

  • Bar chart stacked - strange behavior on display null values

    Hi all

    I'm trying to graph a county of the end dates of the activities over several years by months grouped by project.

    The problem I have is that there is a gap of 3 months where none of the activities that I am tracking complete. The default value for the stacked bar chart is to ignore the columns with no data (in my case it October-December 2015).

    To view these any given month I went to properties graphic and ticked the box "Include Null values. At this point, I get a very strange behavior. Once this option is selected, the legend explodes, showing each project in the database regardless if it meets my criteria for analysis.

    Has anyone another considering that happen? I'm doing something wrong?

    If it's important I'm in the OBI 11.1.1.7.150120

    Thank you for your help,

    Hello

    You have a filter on the list of projects you want to see?

    Based on the way you describe your analysis I guess you don't have any what filter on the list of projects, but some of the filters on the other dimensions/attributes and these filters were limiting the list of projects.

    If this is the case then what you see is not a weird behavior, but everything you've asked your analysis.

    "Include null values" is not limited to the time dimension, it fits any dimension of your analysis, so no filter on projects = all projects.

  • Line chart of several series with staggered data points

    Hello

    App of Hillary graphic sample includes an examples of charts and how to handle null values.

    https://Apex.Oracle.com/pls/Apex/f?p=36648:55

    I came across a scenario which goes a step further. If you have a series with a set of data points and another series that overlap, where a few data points are missing, for example:

    create table graph_lines (series number, thedate date, thevalue number);
    insert into graph_lines
    select 1 series
      ,add_months(trunc(sysdate,'yy'),rownum-1) thedate
      ,log(2,rownum) thevalue
    from dual
    connect by level <= 12
    union all
    select 2
      ,add_months(trunc(sysdate,'yy'),rownum-1)
      ,case when mod(rownum,3) =0 or rownum =2 then log(3,rownum) end
    from dual
    connect by level <= 12;
    

    I get the case where he's going to draw a line between the points that are next to each other, but the gaps it will display just the point

    The idea of 'Null' removal was not all that possible. After testing it out, I found apex will be always generated empty points. Explicitly define the XML to have only the data points with values does nothing either.

    Because I thought it was a really interesting problem, I was wasting so much time on this :-). I was side on the reference guide and the user, modify the XML again and again and again.

    I hoped that, by defining a second category axis and set regional and datetime parameters, change of the shaft in one type datetime and specifying a main grid with every month, the table would be plot my data on this axis. Unfortunately, it seems as if this is ignored - a very frustrating experience. Anychart would just keep trace points with its own calculated intervals.

    Ultimately if I stumpled on a sort of difficulty, although I'm not sure how good it would be. There is a setting that you can set by using the custom XML part that ignores the missing data and the values of interpolation. It works well, but it always displays labels.

  • Blue/green lines acting weird

    Until recently in AE my blue and not green lines acted as they would normally and it raises all sorts of frustration for me.  At first, I thought it was just my new project, but then I started to open old projects allowing to behave normally, and now they are weird acting just the similar new is clearly a problem that happens throughout my AE software not just my project.

    I'll open a project the RAM Preview button click and it takes about 4-5 minutes to load the green line for a film which is 4 minutes and does virtually no animation inside or effects, then the movie will begin playing automatically as it is supposed to when it ends the caching for ram, but THEN! I look forward and noticed that the green line is only at half way through the film so it really only cached in the first half of the film. So, I put paused and then click ram preview again and all executives who have been just cached to ram disappeared (there is no more green line where I waited just 4-5 minutes to get cached) and the green line, which was all throughout the first half don't not turns blue when I try to see it go in the same place It disappears completely.  THUS, it acts as if it is no longer chached RAM or even the drive!  Just the fact that it stops at half way through and behaves as if it cached the entire film (starting in the RAM Preview) is also just weird and proof that something is wrong.  This will happen again and again in different forms or another.  Basically, it's just unpredictable and I can't find a model in the problem then it makes it even more impossible to deal with.

    Any ideas on the issue?

    P.S. I noticed when I changed the RAM Preview FPS in a project, he changed the FPS in RAM Preview for each of them. Is there a way to make sure this does not happen and there just specific to this project?

    The majority of your video clip of work would be done first.

    First works such as iMovie did because they have two video editors (or NLE - non-linear editors). They work with a video stream. This is different from how AE, Nuke and other software compositing - located on full frame, without compression information in pixels. There is a long explanation why you probably don't care, but hope this short helps. The Adobe team is working on this repetition how AE works that will make the preview to be a little more faster/better in the future, but it won't always be like a NLE.

    Now, lyrical videos would probably do for most in AE. But the good thing is that you don't really have much in AE - just a small piece at a time to listen to samples. Set your work area and create a RAM Preview (half brothers, probably). In addition, an important tip in AE, you can press on the. on your keypad and AE will play an audio overview. During the preview audio playing, press on * on the numeric keypad to set markers. If a layer is selected, it will be a layer marker. If no layer is selected, it will be a composition marker. This is a convenient way to appear outside of the audio timing to the AE.

  • You cannot change the chart value axis when there are several types of graphics in a single diagram

    Illustrator can do graphics with bars and lines / columns, for example in the docs:

    http://help.adobe.com/en_US/illustrator/cs/using/images/gr_15.png

    http://help.Adobe.com/en_US/Illustrator/CS/using/WS3f28b00cc50711d9fc86fa8133b3ce158e-8000 .html

    However, when I create a chart like this, I seem to lose the ability to manually set the y-axis using 'override calculated values.

    To reproduce this problem:

    1. Create a chart as in the example, with bars and an axis on the left, lines and an axis on the right. Unlike the example, don't fix the numbers as well as the lines align perfectly - have a go until just less than 20, a up to a little less than 250, therefore it do not markers and the number of divisions on each side.
    2. Try to make the markers and numbers of divisions to the height, so in fact, the side that is going up 20 going up to 25 and has the same number of divisions on the other side.

    Everything I have tried does not work:

    • If I select the entire chart and go to the "Chart Type", I can not set the options for the value axis. In earlier versions, it's gray, in CS6 I can access, but clicking on 'OK' does nothing.
    • If I select the entire chart and chose the type of a chart, I can set options for the axis value, but that the selected chart type, and then applies the entire table.
    • If I use the direct Selection tool to select one of the series and open the "Chart Type" options, changing the options of the y-axis has no effect
    • If I use the direct Selection tool to select all series that share an axis and open the "Chart Type" options, changing the options of the y-axis always has no effect
    • If I use the direct Selection tool to select the Group of ticks axis itself, or the axis line and groups of ticks axis themselves, of axis labels, axis and graduations of the axis line, or axis labels, axis line, graduations of the axis and series of related data, etc., by changing the options of the axis also has no effect

    It seems that this feature is broken and it seems that the example in the manual has been carefully chosen to use a rare combination of numbers where it would actually look right.

    I thought about it. Like everything to do with the horrible ancient neglected graphic Illustrator tool, it is ridiculously clumsy and involves the caution around what is shamefully bad programming for a professional expensive product.

    It is timing - to do things in a sequence of rigid counterintuitive that seems not to work then meets at the end:

    1. Create the chart but, for now, keep all the same chart type. If you've already set to have different graphics types, put the same thing for now.
    2. Select the entire chart and in the main window of Chart Types, set the value to "Both sides" axis
    3. In the drop-down menu, there should be a left and right axis (or top and bottom...). Set the parameters of the value axis for these now. It will look like it does for a single axis, because it will not change the other axis - naked with her...
    4. Select the data series you want to use the other axis using group selection. Go to graph Type and the value of the y-axis to the other and set the chart type that you want. All of a sudden all be put in place.
    5. If you need to change the settings for the value axis, select the entire chart, set the whole chart type to a chart, change the appropriate value axis by choosing it from the menu drop down and the re - apply types of graph as above.

    (the bug is - it should not necessary to set the graphic object to only have only one chart of type in order to access the axis options of value for two different y-axis)

    Thank you

    Dylan

    Hi Dylan,.

    There is a good chance that this is due to differences between your button above States.  Remember, the 'mouse sensitive' area is determined by the graphics are actually visible.  You could get a flicker if a work of art that is visible in the up State is hidden in the over State:

    1. Imagine a rectangle "dyed background" is visible in the high State.  Mousing over this rectangle of course puts you in the over State.
    2. Now imagine this background rectangle is not visible in the over State and neither are all the other charts to this position.  So, as soon as you arrive at the over State, you are in fact no longer at the top of the button.
    3. Since you are not on the button, return you to a high State.  But now you 're (on the button given that the rectangle has reappeared), so you go back to the over... State but now you're not on the button, then... etc.

    (You may have noticed this same problem on some HTML sites where the links change font style and then resizing, in response to the overthrow).

    If you can just twist your work to solve this problem, there is a sneaky workaround solution: draw a large rectangle (or other shape) over your all button to define the area that is sensitive to the mouse.  Now to set the opacity of the rectangle to zero – but leave the eyeball on in the layers panel.  Because the rectangle is always technically visible (eyeball is on), it will always be 'catch' mouse on behalf of key events.  (Just be sure that you share the rectangle in all the States of the button and do the same size across all States).
