• XY graph: traced by point

  Hi my intention is to draw in a XY Chart point by point. Which means for example: I want to draw a diagram of dispersion.

  I first check if the array element meets a certain condition (say if it lies between 1 to 5) if I want draw in red, otherwise, I want to check another condition (say between 5-10) and then draw in blue and so on.

  First I check the State and link it to a structure of matter as each business structure will contain the corresponding color of conspiracy, but it doesn't seem to work.

  Kindly guide me with this.

  Thank you!!

  
  

• Delete locations of XY graph at design time

  Thanks to LabView 8.6

  I inherited several screws maintenance and have met the 'next question' - there are multiple XY graphs, tracing a variety of data and by optimizing things to remove redundant data or unnecessary properties of the XY graph reflect still have 6 slots instead of the 3 that are connected on it. I reduced the caption to include only 3 plots that are actually linked, but properties dialog box still shows 6 locations, both named 'conspiracy 3' and 'Plot 4' and a "V2" Unfortunately duplicate name for what would be the plot 5. Running the VI does not seem to change what contains the properties dialogue box, although it is not all negative effect (within a few seconds of running).

  Is there a correct way to remove the plots exist or is - this something where I have to delete the XYGraph and place a new user interface and connect as usual? My biggest concern is that there is a duplicate name that could cause problems at some point, or that this thing is just lose the memory and the CPU cycles and there will not be a problem until the system has worked for 10 hours.

  I have attached a picture of the relevant connections (the VI is ridiculously huge and unwieldy to post... don't get started me on the ineffectiveness, it's just that I inherited to maintain), but there isn't really anything unusual here.

  All the plots of old who receive more data will not appear, so it is not really so important to remove them. Resize the legend the number of valid locations.

  Yet the current situation is not ideal, that's why I posted this idea a long time ago. Please vote for him!

• Tracing data from two locations on the block diagram on the same graph

  Hello world

  I'm trying to plot data from two distinct processes on a chart.  These processes occur in the order.

  I have developed several solutions, which none produce the result I want.  What I want is for the data to trace in real time each process is running.

  The two processes are functionally identical - one loop "for".  With each iteration of these loops, data is produced and traced.

  The data are plotted in real time, which means that each reference appears on the chart as soon as it is produced.

  However, I am not able to get the second process data on the same graph in the same way.

  The closest I got combines the graphic with a local variable.  This allows the data for the two processes to draw in real time, but the second set of data replaces the first.

  I have attached a very simple test VI showing my problem.

  Any help with this would be greatly appreciated.

  Thank you

  You can do something like this. Is the second process just a continuation of the first? If so, it becomes even easier and you can just to keep construction of the table in the second loop.

  

• Tracing a position using two voltage on a graph signals in LabVIEW

  I am a new user with LabVIEW and I got 4 analog signals with a detector sensitive Position of duo-lateral (PSD) and then I made math on them and then reduce to two (coordinates X and Y). PSD will give the position of the signal in terms of tensions. If the position on the PSD is in the Center then X and there will be zero and the position of the signal on the signal changes the X and Y voltages are changing, so we get the new position. Now I want to do is draw the co-producers of the signal on the DSP on a graph in LabVIEW simultaneously. I'm simultaneously sampling at the speed of 1 kHz.

  Can someone help me with this application?

  Thank you

  
  

• Remove the path traced in XY graph

  The attached VI is an implementation of a transistor output features. I've set up using the basic equations. However, my problem is that the XY graph traces to 0 and then starts a new value of VBB. I don't want which retrace the path. I mean, is that, upon completion of the inner loop the external value is updated. Because the inner loop starts agains by 0, I don't want the latest iteration of the inner loop line to the new interation of the inner loop.

  How can I remove that. Help, please

  Insert an additional point containing NaN in the data, it will break the line.

• How many curves can be traced on a tiara 2D graph

  Hello world

  I want to draw the curves of some(360+) on a 2D graph. I got the results for samples that are measured at different temperatures. I had no problem to trace the curves of all devices for a temperature. But what I noticed when I tried to trace the curves of all devices for all temperatures, it is that it does not work. Tiara (ver.10.2) gives an error if the number of curves is higher than 250, how is this possible? Is this a program limititaion which can be fixed with a patch or service pack, or I do something wrong?

  Thanks in advance

  Hi fscommand.

  From DIAdem 11.1, the maximum number of curves on a graph given in mode or REPORT is 250.  This has been the case for many years.  This restriction may disappear in future versions of DIAdem, but I do not expect it to disappear in the period of 2010.

  The solution is to overlay the 2 graphics, on the other.

• Programmatically hide a tracing on a mixed graph box

  Hello

  is it possible to programmatically hide a plot on a mixed graph area?

  Izabela thanks!

  In fact, I read the height of the viewport and scaling then areas of land necessary to fill the whole window. In this way all unnecessary field areas have been moved to the bottom and are not visible. To prevent the user from scrolling down I've hidden the scroll bar of Y.

• First HP axis line bug in Boolean expressions (Adv. Graphing App)

  When the graphic representation of an inequality and excluding a part of it using Boolean expressions, there is a bug where the first will be graphic axis lines are part of the solution by using 'AND NOT '.

  An example of this is that if you were to graph a circle of RADIUS < = 5 and remove a circle of RADIUS < = 4.

  Example:

  V1:=(X^2+Y^2<=5^2) AND NOT (X ^ 2 + Y ^ 2 < = 4 ^ 2)

  Axis lines X - there exist in the excluded (X ^ 2 + Y ^ 2 < = 4 ^ 2) and can be traced back as if it were part of the solution of V1.

  Interestingly, if V2 is set to be equal to V1 (X - 0.5, Y - 0.5), axis lines are no longer aligned with the axis of the grid, but are rather shifted-0.5 on the X and Y as well as the rest of the V2.

  In this case, the equation can be modified to work around the bug by removing the NOT and change the sign of the circle radius 4-more of:

  V1:=(X^2+Y^2<=5^2) AND (X ^ 2 + Y ^ 2 > 4 ^ 2)

  Does anyone know if there is a reported bug?  Where I might be able to look to see a list of known issues?

  Thanks for the detailed examples. It took me a while to see what you were talking about, but once I did I had the info the graphic calculator expert.

• Mouse movement accelerates graphic tracing activities!

  Salvation OR,.

  I tried to run a project collecting data rs - 232 (incoming data to 10msec frequency... 20 bytes each 10msec). The LabWindows environment seems to work more efficiently (faster) if I move my mouse over the plots (without even clicking it!) as opposed to a regular path in the tabs pane. I have used a TSQ + thread concept pool to run my data collection and plan update. Can someone help me please on the fastest way to plot the data. I was informed earlier not to use a timer in GUI for tracing purposes with data acquisition high speed and track! I can't understand why the plot is faster when I move my mouse over the graph as opposed to simply let draw normally! I use a WinXP machine.

  Kind regards

  Combination of Roberto and Kanchan,

  1. the configuration of the machine: Pentuim processor 2.8 Ghz, 1 GB Ram, Windows XP, Labwindows CVI 2009.

  2. the SetSleepPolicy concept seems to have solved part of our problem with the refresh for the application rate... we are very grateful for this entry.

  3. for all other users of LabWindows CVI, TSQ concept takes a period of time to place the data in the queue... so if you run periodicity 10msec to packages of process and say the queue itself write 50msec... a good idea would be to combine 5 packs and then write to the TSQ... earlier our packages were ongoing in the queue of the port COM RS - 232 by the thousands for a minute run... We took entries OR to reduce less than five packets for the same amount of execution time... temporal analysis of the code functions allowed us also to rework our code by removing the function calls that sometimes take a long time to process system events, sync expected etc.

  Thanks a ton Roberto... I might just have to meet my deadline of the project now

• Mixed signal graph - data digital unable to see on the graph

  Hello

  I'm tracing analog and digital data on the graph of mixed signals. I'm not able to see numbers on the graph, but when I export data to excel it shows all digital plots also. According to me, Miss me some settings.

  Please check attached VI for reference and let me know if anyone knows the solution

  Kind regards

• Track of functions in a 2D on a graph table

  Hey all,.

  As an exercise, I am tracing 2 functions placed in a table 2D on a chart, but for some reason any figure shows only one of them.

  The functions are: y = 5 x + 10 and y = 6 x - 10.

  I really don't see what I'm doing wrong here, could someone give me an idea more?

  Thanks in advance,

  Michiel

  Based on your code, I think that what you really want to use a table, not a graphic.  A graph keeps a history, so he just keeps adding on the data.  A graph is overwritten every time that you write to the Terminal.  If you were only graphic single point for each parcel.

• Zoom in or on the graph during execution of VI

  Hi all

  Currently I have a Subvi popup that contains multiple locations of data collection for the user to view.  When the user clicks on the 'Stop' button on the Subvi, this sub - VI will close.  So I section tracing the program in a while loop.  I believe that this is the reason why I wasn't able to use the graphics palette to make a zoom in and zoom out right?  Should I just leave it track section out of the while loop then?

  Thank you

  Lynniz

  Place the property within a structure of case node and turn it back on once the iteration Terminal is "1". (not zero!)

  And please put a small wait inside the loop, there is no reason that he should turn that fast. (Given that the data never change in your example, the earrings inside and around graphic terminal belong outside of the big loop.) However, I guess that your real application differs )

  NOTE: you could also use the antiderivative "of first broadcast?" or allow it when [i] = 0, but in this case, you would need a small sequence structure in order to ensure that this happens after ther graphic terminal is written for the first time.

  Also note that the xy graphs take complex data, simplifying the wiring and data structures.

• metal theme waveform graph

  Hello

  I use the metal theme to design a façade of Labview.  I would like to plot x, y of the data on a chart, however, there is only a graphic of waveform and waveform Graph available in the metallic theme.  Can you help me in tracing the x, the data is in the curve of waveform in the attached VI?

  Thank you

  hiNi.

  You can customize the graph of the metallic wave and replace it with a XY Chart and set some properties to match the waveform graph

  Or let me do it for you

• 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
