• Locking of the limits of a graph on the front panel.

  How can I lock down you the limits of a graph of façade?  I don't want the user to select the scale and the type that will resize itself for the plot.

  I use the graphics property node to set the minimum and maximum on the scale, but it is still able to play with them.  I'm trying to show you idiot

  There is a property for editable scales node. You can always change when the VI is not currently running, but she she blocks during execution.

  

• First Graphing Calculator Identification of old Version of main material has

  Hello

  I tried to update the firmware to the latest version (2014-07-02 (6031)) on my graphing calculator of premium without success, the release_info.txt file which indicates (for 2014 03 31 (6030) firmware version):

  There is limited between that backward compatibility and earlier releases.

  First older hardware (revision A) supports this version, but the stream without thread-to-unit and data functionality is not supported on previous models. In the first screen HP help > revision of material appears with the software version information.

  How will I know if my calculator hardware number is A revision material?

  Is the version of CASE the number of material?

  Thank you very much

  H.

  Hello

  All primes of HP are upgraded to the version 6030 (note that 6031 is for PC emulator only). It's just that the material has a problem with certain communications.

  Firmware version prior to 6030 (5447 and older) do not show the hardware version in the display 'a way'.

  When you upgrade to 6030 the hardware version will appear on the display 'a way'.

  Alternatively, you can determine the version of the material from the model number (located on the back of the box she approached, the bar code):

  NW280AA is A revision material

  G8X92AA is the review material C

  In addition, the following process is recommended for the upgrade of the premium:

  Install the connection from the CD Kit.

  Once installed the connection, update the calculator.

  The following method is recommended:

  • Connect your HP Calculator first via the supplied USB cable (connected directly, do not use a USB hub)
  • Start the HP connectivity Kit
  • Click the tab of the calculator
  • Right click on the name of the first HP you want to update (it would be that you connected before starting this procedure)
  • Write down the version number, and then click the OK button
  • Click the Help Menu and select Check for update
  • Look for the pop-up box to update, check the version number that is newer than the one you want to update.
  • Then click on the download button
  • That's it, you will see the update being loaded and installed on your calculator screen. Don't click too quickly out of the HP Connectivity Kit, wait a minute or two after the completion.
  • In addition, there are a step in the connectivity Kit where it is advisable to back up the version that you had before the procedure, just in case. This way, you have a way to cover again.

  Kind regards.

• QUESTION: SE 2012 data display returns to the time graph each time

  Hello

  I have SigExp 2012.

  If I try to add a data view and make a pledge of graphic style, thermometer, etc., as soon as I have the right up until it clicks, add my TC chain, the data view returns immediately to a graph time.

  In addition, even if I use the graph of time, once I added the signal, it only let me see the string in a table, a chart of time or a waveform graph.  Those are the only choices.

  If I use a graph of time or a band of waveform graph, it does not read the signal correctly, but I can not configure the data view, the way I want it.

  Is this a bug or I do something wrong?

  Thank you!

  This occurs when you try to change the display of a signal in its raw format "waveform".
  You must convert your signals in scalar format. To do this simply add an amplitude and levels step (under: analysis > measures Time-Domain). Drag this DC signal newly converted to a new chart and right click on the graph to change the display.

  Honestly, I'm not sure why raw waveform signals are inherently limiting viewing functionality, but in such cases, it is.

  You can also; According to the devices on which you use and the order in which you add to your DAQmx Acquire, some default signals step to scalar signals without having to convert.

  See the attached screenshot and you'll see how the icons are different between the waveforms and scalar signals.

  Hope that helps

• Chart WPF: How to get the limits of PlotArea and axes

  I can't find explicit methods to get limits of PlotArea and axes.

  Please let me know workarounds if they are available. Actually a post explains how to get the PlotArea limits using RangeCursor. Are there alternative means for shafts?

  The photo below shows what I did in WinForms with the methods GetBounds and HitTest. I would like to draw the ornaments on the chart in WPF.

  

  I have attached a code example of this look ornaments around the plot area and the scales.

  Note that this relies on implementation details of the current version of WPF controls for the ornaments of the scale, as it was more effective than gradually points to test in the graph using the GetScaleAt method. We have intentionally left much of the underlying primitive types with a minimum documentation, like us they have changed in the past and may change in the future. Although these exact members can be removed in a future release, we do not expect to provide an equivalent function and stabilize the primitive API over time.

• Expression evaluation limits step

  I'm just trying to understand the point at which the step limits expression is evaluated. I'm trying to define the limits of a test of numerical limit based on an expression. I'm passing the context of the sequence for the LabVIEW code module so that the VI may determine the limits to set the colors of parts of pass/fail indicator and for certain other purposes.

  The problem I have is that it resembles the step limits expression has not been evaluated at the time wherever the context of the sequence is passed to the VI, which means that the calculated limits are not available. Is this correct? If so, does anyone have suggestions as to how I might be able to get around this?

  Thank you.

  Adam

  Hi Adam,.

  The following graph shows the order of execution of the teststand steps.

  

  I believe that the evaluation of the expression limited on "steps of numerical limit test" occurs during the evaluation of the expression status (so the last part of the stage).

  Another solution would be to create your own custom step type and include a custom "step first substep for your personalized step step" (I think I just broke the world record for most uses of the word 'no' in a sentence )

  However, I think that you've already found the solution more practice/simple/elegant. Yes, Bravo to you!

  Thanks for your time. I hope that gives a little clarification.

• Lag when you draw a square by using the property plotimages.back on XY graph

  Hello

  I'm developing a simple program where you enter 2 vertical sliders on a XY chart by selecting coordinates X and then it should highlight in yellow the area between the two mentioned sliders.

  The issue I'm having, is that even if the program is inspired by the square on the graph, there is a shift, which I can't get rid. I checked the input coordinates to draw the square and they seem correct, however, the gap is still there...

  Please find attached my program, thank you very much for your help!

  Well, I found the reason. To eliminate the offset, you must get the graph XY plot area limits and subtract 'top' and 'left' your coordinate of the cursor values

• Graph XY - Autoscale + fixed margins

  Hello

  Total newb here.  I am currently draw a circle on a XY graph where the RADIUS can be changed, so I have the x and the y axis set to "Auto scale".  However, the autoscale makes the edge of the circle go right up against the edge of the high, low, right and left of the plot area limits.  I would like to add a 'margin', mainly for aesthetic purposes, so there is a certain fixed amount of space between the traced circle and the limits of the area of the plot. Hope it makes sense.  I enclose the photos that I created with autoscale OFF to try to help illustrate what I'm after here.  Any help or advice are appreciated.

  Kind regards

  Doug

  Hello Doug,

  You should be able to add a space of memory buffer by activating the option "Loose Fit" in the >>(x,y) right click menu of the scale.  This will be round the autoscale to multiples of the scale factors 'Multiplier' their value set in the property window of the scale.

  Of course, you will still need to make an informed decision about a multiple what good would be, and it depends on the range of sizes you will need to display.  If you need to go more granular or dynamic that allows (for example, always scaling the chart in 1,05 x the radius of the circle), then Yes, you will need to use the nodes property of graphic range.

  Kind regards

• Placing several sets of data on a graph (LabVIEW for Excel)

  I read in a 2D array (first rank values of the x axis, 2 values for the value axis in line, 30 columns) of a number of excel files. With each iteration of my loop for example, I read in 1 all of these 2D table data, and I'm tracing the curve (using Excel Insert graphic) before I close this file and move to the following.

  I want, however, must be able to generate 1 chart at the end with all sets of data together. So far, whenever I'm iterating, new data erased the old, and in the end I only get 1 set of data (the last game) on the 1 graph.

  I searched through the Forum similar topics, but 1) I have all my data read or typed into a nice big table, they come in the iterations instead, 2) my data values do not share the same values for the x axis, while the beach is almost the same (from 0 to 1) and the number of data points is always 30 (3) I don't think I can use shift registers because all my data is obtained in my loop, when I open Excel (also in the loop) files and read them, so I did not 'Original data' to initialize the shift register.

  Any suggestions on how I was able to read the data, graphics, read the new data, then graph on the same graph without losing my old data?

  Thank you!!

  Kalyie,

  You may need to force your data to have the same category axis.

  Another option would be to insert data in excel instead of a graph. From within excel you could have a set graph in place who knows where the X values and are there for each data set and it will draw it automatically.

  You can also try messing around with the Graph.vi of update to Excel.

  I had limited success with the Excel update Graph.vi, but worth a visit.

  Thank you

• Limits of drawing on my wave form

  I have two waveform graphs that display a live view of my oscilliscope.

  What is the best way to draw two limits of amplitude on the axes Y Parallels? I can do this somehow property nodes? or do I have to do these multiplots of waveform graphs and add dimensions to my table-y?

  Thank you...

  You have 2 options (or more).

  The second is by FAR easier than the first, but I'll show you both anyway

  (1) build an array to a constant value, which would be your thresholds and draw as well as your data.
  This will draw the boundaries above and below data is be postponed.

  (2) create cursors. Nodes property allows you to assign their values are based on thresholds.

  See the attached VI.

  All the code in the while loop on top is option 1.

  The ridiculously simple property node is option 2.

• mixed-signal graph size automatic

  This seems simple, but is there an option that will automatically format all the graphs on my graph of Mixed Signal to the size of my VI? For example, if I increase and decrease the size, the graphics remain a constant size and I would scroll to see them. Secondly, that all graphs have the same vertical height, instead of me manually by dragging the separator to try to make all equal in size?

  Right click possibility and also space all the graphs and auto fit all graphs would be very practical! I can't find the option for her.

  Image attached showing the spacing I'm talking about.

  Thank you!

  Hello

  This can be done programmatically with the nodes property.  The trick is to use two nodes of different property of the to do.

  We must first define whatever parcel we want change to be the active plot by using the Active plot area property node.  We can then define the limits of this plot by using the node property parcel size of the area, which is located under plot area > size.

  

  Good luck!

• Limitations of data Dashboard App

  I have an application that requires a central logging Windows PC/Labview make data available for viewing on the screens of multiple users.

  Screen touchscreen devices offer the best solution for the environment and I assess tablets under the dashboard of data app vs Windows touchscreen tablet PC running labview code.

  The requirement is very flexible because users must each be able to see a selection of a large number of variables against each other or time and also to choose the period of time for display.

  I can see the application of the dashboard of data is in constant development and I tested it with data from the trial, including several line plots and be able to zoom and scroll the screens as well as control static variable to select the data to be represented graphically.

  However I come to the conclusion that I need to go the Tablet full PC channel to use the full power of Labview to make a user interface appropriate.

  I would like to just following current limitations of the dashboard data confirmation:

  (i) I can only have one axis Y multiplot graphs/Charts. (and cannot specify the different colors of the locations)

  (II) it is not possible to simply provide a timestamp on the X axis.

  (III) such things as 3D curves are currently impossible!

  (IV) I get about 20000 points for each of the variables at least 10 and this seems to slow down the 1.5 GHz/1 GB of RAM Dual Core tablet that I currently use. Power/memory of treatment more that would help?

  Thanks a lot for reading.

  You will probably get the best response if you post to the Office of dashboard of data.

• I need autoscaling on a graph XY to ignore a parcel

  I'm doing the autoscaling to ignore one of the three locations on a XY Chart.  My program trace a set of data points, that approach and exceed a critical level.  My chart has three parcels: under the limit points are green points, points above the limit are red dots, and the limit is a horizontal dotted line extending between two points.  Initially, endpoints of the line have been established in the vicinity of the x-values of data.  Autoscaling worked very well, of course, but the line analyses as well as the data they are traced.  This limit is a fixed value, I like the line to stretch completely on the screen and stand still.

  To this end, I put endpoints beyond the limits of the x values.  Now, auto-scaling of the tracks with the endpoints of the line and the actual data are compacted in the middle of the graph.  Is it possible I can forward the autoscaling only with data points and ignore the line, or is the best option, just write my own code, autoscaling?

  Thank you!

  You could wirte your own automatic scale, but I think is easier to do something to change your horizontal line of a parcel of a cursor. You can use the list property of cursor or active (the control graph) the cursor property to control positioning and the color of the cursor, and you have not to worry ever its end points (there no).

• Trace graph XY forever hiding other parcels

  Hello

  I use a graph XY draw certain limits. These limits are indicated by the plot 0 and parcel 2 , that's why I put them to "Fill in positive and negative infinity" respectively.

  It is, I now have another plot (trace 3) to display that fall into the 'limits' designed by plot 0 and 2. The result? Parcel 3 is covered almost entirely by the other plots with the "fill up to.." option.

  TL; DR: is there a way to make the plot 3 display along its length without being under the filling for x infinite plots?

  Current result:

  

  Expected result:

  

  Changing the order of the plots and setting limits to the end.

• Create horizontal lines on a graph

  I'm looking to create horizontal lines on my paintings of waveform. I know that I can't use the cursors on a chart, but I want to find a way to draw lines on the y-axis of a graph (chart) of a control on my front. The reason is: I am in a position a sinusoidal signal that changes in amplitude due to the deformation of a material. I need to adjust the length of these horizontal lines using as reference.

  I understand that I could use the limits of the curve because of it, but then I wouldn't be able to tell how long out of bounds, I. I am a super novice to Labview and you guys have been such a great help with all my endeavorsso far. Any suggestions?

  Draw several lines in the table, where two of the parcels are borders. I don't remember the exact requirements, but you can probably do it by grouping the values or the construction of a table. Check the contextual help and the examples in the table.
