3D Plot

Wenn ich in einem Labview file zwei 3d Plot gleichzeitig benutze werden diese nicht mehr angeszeigt. Kann es sein das meine Systemresoursen zu gering sind ?
Hier meine Daten

Intel Core 2 [email protected] 1,98 GB RAM

Hi,
habe mir dein vi mal angeschaut, wenn du den 3d Plot vorher in einer while schleife hattest, hast du dann alle Punkte einzeln gezeichnet? Du musst immer die komplette Grafik übergeben. Ausserdem wird in einer whileschleife bei jedem Aufruf der 3D Oberfläche diese neu gezeichnet. Ähnlich einer numerischen Anzeige die die Anzahl der Durchläufe ausgibt. Kannst du auch nicht mehr ablesen.
An deinem Programmierstil erkenne ich, dass diese whileschleife sehr schnell durchläuft, da du keine Timings verwendest. Du solltest in einer whileschleife immer! Timings verwenden, da diese Schleife deine Prozessorauslastung sonst auf 100% hoch treibt.
Du kannst dein Programm auch noch effektiver machen, indem du nicht so viele verschiedene Datentypen miteinander kombinierst. An vielen deiner mathematischen Operatoren und vi findest du so kleine rote Punkte, das sind implizite Typwandlungen. wenn du zum Beispiel einen U8 mit einem U32 Wert addierst, und dann in einen Anzeigeelement ausgibts, dass double anzeigt, dann müssen beide Werte konvertiert werden. Die implizite Typwandlung dauert sehr lange (relativ), besser ist hier die explizite, findest du unter numerisch>>umwandlung.
Wenn du das alles beherzigst, gewinnst du schonmal eine Menge Systemressourcen. Aber wie gesagt daran liegt es in deinem Fall nicht. So kleine Grafiken bemerkt das System wahrscheinlich nicht einmal.

How can I represent more than one plot in an only one chart?

Hello everyone,
i got a code where I don't understand how to represent more than two plots, with different scales each, in the same waveform chart.
As brief review:
* 2 adquisition data wired to Bundle
* wire from Bundle to waveform chart.
* options of th chart: stack plots.
I've tried to expand the Bundle but the problem is that I'm wiring a 3 element cluster to a 2element cluster chart. I don't understand how to upgrade the chart...
(there's the two plots in each chart)
(there's the code, where I've already tried expanding any bundle and wiring other signals, then wiring the bundle's output to the chart)
I think if I could add more scales, it will be possible to plot three plots on the same chart.
Thank you for your time
Marcelo A J

Since you are dealing with waveforms already, I think you actually want to have an array of waveforms to go into your chart. You also need to map the plots to the scale that you want to use. You can do that in the plot tab of the properties window.

How to get lab view to display my plot in DB

hi guys
i desigED n an operational amplifier to determine the gain product band width using a 741 chip and the gain of the circuit is 1000, meaning that the gain bandwidth PRODUCT will occur at a frequency of 100hz. but i have a problem, when i start the frequency sweep from the function generator from 10 hz to 100Khz which IS the final frequency value i have set for the program. when the lab view program stops and i export the data to excel sheet i will be getting the DB axis value in a SMALL VALUES AND IN DIFFERENT UNITES WHEN I PLOT THE GRAPH USING EXCEL, while the frequency is in log10.
pls can any one tell me how to solve this problem to start getting the right cut off frquency on the graph. find aattched my vi and the excel data from the vi that is in a different unit not in DB

thanks Jeff Bohrer for your reply, what i mean is the y-axs of the plot is in DB aleady, but when i export the data to excel i will be seeing the gain in 0.8, 0.7,0.4 which is not normal, which will not give me the -3db point of the gainband width product of the circuit
What you want to do is plot the Log(10) of the frequency on a linear axis!!!!!!! The export - exports the values not the axis scale. exporting a log(10) of the Y axis will export the log of the axis- (of couse, you could change the graph axis scale in Excel too...... but)

Hi rhiesnand,
right now you add 2 new rows to your array.
The solution is to concatenate both row parts to one bigger 1D array before adding that array as new row to your 2D array!

How to let the user define the colors for each plots in the graph (I use LabVIEW 7)?

How to let the user define the colors for each plots in the graph (I
use LabVIEW 7)?

Hi,
Take a look at this example, it uses property nodes to select tha
active plot and then changes the color of that plot.
If you want to make the number of plots dynamic you could use a for
loop and an array of color boxes.
I hope this helps.

Plot a chart dynamically based on the values selected

Hi All,
I have some requirement like this i want to plot a chart . The chart should change dynamically based on target_name and date. What type of UI should I use ? I tried using multiselect or shuttle for choosing the target_name and date picker tool for date once i choose all this the chart should appear. Can I have a custom button called submit so once all the values are entered it plots chart ? Please help me out with our ideas.
Thanks in Advance

Hi,
Using the dependent value sets you can govern the values which can be selected based on a specific value selected in a particular segment. Example if Country name is selected in segment 1 then specific states names as per the country selected can be displayed in segment 2.
As per the requirement described you want to enable different fields based on the value selected in segment1, currently there is no standard mechanism available to enable/disable fields based on a value and you will have to do an extension/customization to meet this requirement.
Thanks,
Sanjay

Line width on plot and on plot legend not matching

Hello,
I wrote a program that "highlights" (changes the linewidth to 4) one of two plots using a boolean switch. However, the corresponding linewidth in the legend does not always show the same width as the plots value. For example, if plot 0 is thick, and its legend is thick, and plot 1 and its legend are thin, then I select plot 1 to become the highlighted one, plot 1 in the graph will become thick, but either its legend will not become thick, or plot 0s will remain thick, while plot 0 on the actual graph will be switched to thin.
Thank you for any help you may be able to provide.

Hi M.Bobby,
I can see the same behavior on my machine as well. This was reported to R&D (238303 CAR ID) for further investigation. R&D is currently investigating this issue. A possible workaround is to hover over the legend to make it update. We are sorry for the inconvenience, and appreciate your feedback!

Display real time data on a plot in a sub VI and main VI

I am building a program to measure and plot real time data. Program has several steps so I build few Sub VIs to make it simple. My problem is I am plotting real time data in my SUB VI(it works fine), but in my main program when I try to get the same plot its not real time data plot. Plots appear at the end of the program. All tips and help would be greatly appreciated. Thanks

LabVIEW program is based on DATA FLOW, now, until the subVI will finish execution (while loop will be stopped), the execution in Main VI will not proceed any further.
If you can pass the reference of 'XY Graph' inside the subVI, you'll be able to update the plot (placed on MAIN VI) from within subVI.
Find attached example for your reference.

Data acquisition and waveform graph plot

Dear All
My signal is out put of current transformer which is 2v dc. I succesfully configure usb 1208fs with labview8.2. Now I want to plot my input signal on the waveform graph in frequency vs amplitude(db). Can any one guide me how can i plot my data?

Hi,
Could you strip the VISA stuff and re-post your VI so I could run it and see where is the difference coming from. A few observations though
1. Always try to wire from left to right and top to bottom so that your block diagram code is readable.
2. A waveform graph gets completely redrawn everytime you give it soem data ao it is typically used outside any loops. If you want to display a waveform inside a loop, it is better to use waveform chart.

How can I update single plot in multi plot xy graph?

Hi all,
I'm working on an HMI "front" for a larger acquisition/analysis system, that includes continuous performance monitoring of a turbine. The results of the measurements are stored arrays of contour lines, that represents turbine efficiency and guide vane openings. This analysis is all performed in the background. In the HMI, the performance data is loaded from file when the specific "report" is requested, and is plotted in an XY graph. I would like to indicate the current operation point of the machine by using a plot that is a single point. Thus, that point's position among the contour lines indicates the current performance of the turbine. This point is updated once every second, while the performance data remains the same for considerable amounts of time between recalculations (days to weeks).
Is there any way of updating the value of a single plot in a multiple plot XY Graph without having to redraw all the plots?
I've tried using the "Active Plot" property, which doesn't work.
My current solution is to keep all the data as input to the executing while loop and replace a subset of the plot array, but that of course requires the entire rewrite every time the operation point plot is updated.
Best regards,

Go to Solution.

You cannot redraw a single plot. If you want to update a single plot, you need to retain all plots in a shift regsiter and replace the data of the desired plot. However, your problem seems much simpler than that. To show a single point on a nearly static plot you have several options.
You can use a cursor that is controlled programmatically (the style can be a point, don't allow drag).
You can use annotations.
You can use the "plot images" feature that allows you to use image commands to draw anything on top of a graph.
None of these ideas require a redraw of any data.
I think the cursor idea is probably the easiest and most appropriate. Just use a property node with the following properties:
active cursor
cursor position x
cursor position y

Plotting of graph with more than 4000 data points in Excel

Hi All,
I am fairly new to labview world. I am trying to plot out line graphs of the results from my program into Excel worksheet. I have huge set of data points(10000) stored in each of 10 different worksheets in MS Excel workbook. I am trying to compile results into last sheet as graphical representation of all the various dataset into 10 different graphs.
My problem is that I am getting error because MS Graph does not allow me to plot more than 4000 rows or datapoints. Is there better and cleaner way of programming this? Or if some one can provide an example of how to handle such case. I'll appreciate any help.
My goal is to able to plot one set of data 1st then I will be able to run through various worksheets to compile into standalone results.
ERROR MESSAGE: "Report Generation Toolkit: Graphs you create or edit in Microsoft Graph cannot contain more than 4,000 rows or columns, including row and column headers. "
Also for example if we run Line Graph example and change the # of data points from 100 to 4000, we get same message.
Error -41114 occurred at NI_ReportGenerationToolkit.lvlib:Excel_Insert_Chart.vi -> NI_Excel.lvclass:Excel Insert Graph.vi -> Line Graph (Excel).vi

Hi Dennis,
I am collecting waveform data from oscilloscope using labview in both data & graph format. So my program collects data for a particular operating condition & then saves the data on a worksheet. After it loads new operating condition & goes over same cycle. I have to save all the data points in excel for different use cases, which I am saving in different worksheet for each specific operating condition.
Since I already have data saved in excel at the end of test, I am trying plot each use case in the same report for study & presentaion after tests are finished. I have not been able to do so. I read the post which you have mentioned, seems like newer excel or labview version have same issue. I am using LV 9.0
I will try using decimation but if you have any better way of handling this problem, I'll appreciate if you can share that.
Thanks for your help.

Using LabVIEW to Generate an XY Graph of Multiple, Indexed Plots?

Hello,
I have written a LabVIEW Program (using 8.2.1) to characterize FETs using GPIB instruments. At it's most basic level, the program sets a voltage across the Gate-Source terminals of the FET, sets a voltage across the Drain-Source terminals of the FET, reads this second voltage, and then reads the Drain-Source current. The Drain-Source voltage is then increased, the current read, and so on. In this manner, the Drain-Source voltage is swept from 0V to some defined maximum (dependent on the FET being tested) and an array of data (I_{DS} vs. V_{DS}) is generated. The Drain-Source is then reset to 0, the Gate-Source voltage is increased, and the entire process is repeated.
My problem is this: I need to generate a single Graph (I think it should be XY, but not entirely certain), that plots all of these IV curves (each curve for each Gate-Source voltage) and indicates the Gate-Source voltage for each curve (in an indexed legend of some sort). Does anyone have any suggestions about how I should do this? My program is entirely based on For Loops and Sequence Structures. If you need a screen shot or want me to upload the program, please let me know. Fair warning, though: I am a LabVIEW novice so while the program functions correctly, it is not the prettiest in the world.
Thanks for any help you can provide.
Michael
P.S. I searched the forums and didn't find this question already posted. If, however, it was and I just missed it, could someone direct me to it? Thanks.

Vincent, Jon, and Andrew:
I still need some help. I used the 3524.vi Example for the XY Graph: x-array, y-array definition to generate the kind of multiple plot xy graph that I needed. My problem now is I would like to re-index the plots so that they are labeled according to the Gate-Source voltage I am applying. Each curve has its own, distinct Gate-Source voltage and I would like to label each curve with its Gate-Source voltage. Currently, the plots are labeled in the legend: Plot 0, Plot 1, Plot 2, ... Plot n.
How should I go about doing this (is there even a way to do this)?
Again, any help would be greatly appreciated.
Michael
P.S. I have attached a copy of my program to this message. As I said, it isn't pretty, but it works so far. Hopefully this will help you in forming your suggestions.

I'm running a full updated Arch x86_64 release.
Any suggestions?
Thanks in advance,
Roberto

Hello BajaBoy,
I think it would be easiest to figure this out if I had the data to look at. If you can send this too me (I will treat this confidientially and it will be deleted after we got it to plot) please sned to me me directly at National Instruments.
My email address is my: first name DOT last name AT ni DOT com (no middle initial!).
We'll get back to you with an answer the same day unless we run into the Thanksgiving holiday before we get this.
Hope that helps,

How can I change oval shape applet to (plot)

Hi this is not my code so, the orignal code is freeware to www.neuralsemantics.com and is Copyright 1989 by Rich Gopstein and Harris Corporation.
The site allows permission to play with the code or ammend it.
how could I modify the applet to display (plot) several cycles of the audio signal instead of the elliptical shape. The amplitude and period of the waveform should change in accordance with the moving sliders
