Change properties in stack plots

hello
I'm using a waveform chart in my VI (labview 6.1).I need to display three graphs with diffrent y-scales.
So I chose Stackplots. The result is one chart with three diffrent output windows. So far so good - but now I need to change the properties of the graphs individually. Primarily I'd like to change the way the displayed points are interpolated.
I've searched for the place where to make this changes but all I found was a way to adjust the first output chart. All other output windows of the stack plot remain with the standard looking. maybe a quite stupid question ...
thanks in advance for any help

You need to use/set the "Active Plot" property as per the attached.

Change properties inside dynamic stack plots

Is there any way in LabView 8.2 now to change the properties of indicators inside an array or cluster? I want to change the properties of the waveforms inside DynamicStackPlots (http://zone.ni.com/devzone/cda/epd/p/id/3024). I see on this forum back in 2005 this was last discussed. I have also tried making a cluster of waveforms (instead of an array of clusters) from which you can at least separately access properties (allowing you to make specific waveforms not visible, yielding dynamic stack plot functionality). But you STILL cannot modify, say, the plot min range, label, scale... etc.
All ideas welcome!
Thanks,
Adam

Hi, Adam.
This question seems to pop up every once in a while. The answers are different for arrays and clusters:
Clusters
You can access the properties using an explicitly-linked property node (IE, one that takes a control reference as an input). You can obtain a reference to the controls in one of two ways:
- Right-click on the control (inside the cluster) and select Create»Reference.
- Create a property node for the cluster and access the Controls[ ] property. This will give you an array of references to the controls inside the cluster, and you can pass that into the explicitly-linked property node. (You may have to use a To More Specific Class VI if you want to access properties that apply to only graphs.)
Arrays
Since arrays are for holding a large quantity of indentical data types, the properties for all elements of the array must be the same. If you really want to sidestep this functionality, however, you can always create an array of references to controls. If you wanted to do that, you'd have to create all your controls individually and then create references for them one by one. Once the references are created you can pass them into a Build Array VI. To alter the properties of any particular control, you'd use an explicitly-linked property node and pass in the appropriate reference.
Let me know if any part of this isn't clear. Have a nice evening!

Changing y-axis in chart stack plot

I am using LABVIEW 5.0.1f1:
I plot 8 values in a chart as stack plot by bundeling the values. During
running programm I want to change the y-axis of the 5th value (changing maximum).
But if a use attribute node of this char and select "active plot"=5 and "y
maximum"=40 only the 1st plot window of this stack is changing its y-axis.
How can I modify the 5th plot window?

I have the same problem, did you find a solution?

Stacked Plot y-axis property access.

STACKED PLOT Y-AXIS
I have a stacked waveform chart showing four plots
Each plot correctly appears on a different sub-plot
I can use the set active plot property to loop through the four plots and change their names, visibility etc.
I can also read which is their active y scale index which corresponds to the plot index (i.e.both 0-3)
BUT
When I try and change a y scale property (e.g. label>text) it only ever changes the top sub plot label
I have tried forcing the active Y-scale index also to no avail.
I have also tried an overlay plot with 4 different y-axis and have the same problem.
HOW DO I SET TEH INDIVIDUAL Y-SCALE PROPERTIES ON A STACKED PLOT?

I made 2 small modifications to your VI, take a look at the attached.
First you needed to set the active Y scale rather then setting the index. But more importantly the property node you are using to set the values is linked to the wrong graph.
Let me know if the attached does what you where looking for.

How can I change the color of plot in a waveform chart and graph?

There are 4 plots in a waveform chart, from plot0 to plot3, and I want to chang the color of plots dynamicly up to my needs when the VI is running.
For example, as show in the picture, i want to set the plot0 as RED, and plot1 is BLUE, plot2 is YELLOW, plot3 is GRAY.
If there is only one plot, i can change it's color, however when there are more than one plot, it fail.
How can I do it?
Thanks

Hello MilkyStone,
first you have to set the active plot, then change its color (or other properties). All that is done using property nodes.

Stacked plots problem in exe

Hi,
Ive got a problem with creating .exe application where 2nd chart functioning properly.
2nd chart is in subpanel as a stacked plot. I pass via main form numbers of stacked plots. In builder it works perfectly, in .exe not at all..
Any ideas?

Ok sorry I didnt explain well whats the point.
There is no problem with properly "refreshing" of subplot - works fine even without static reference(but thanks anyway, I missed that).
I cannot changed the number of staked plots in the screen(constanly 1) - in editor mode it changes according as number of flaged plots.
The problem is show in the pictures below.

Dynamically resizing stacked plots depending on visibility of scale

Hi,
is there a way to change plot width in a chart with stacked plots, depending on visibility of scales and number of digits of scales _and_ without resizing width of the chart when all scales are invisible?
The problem: when all scales are invisible and the number of digits increases, the chart's width decreases and the scales move a little to the left.
Thanks a lot in advance.
Cheers,
Martin

Hello Martin,
Could you please attach some sample code of your question. Also, if would be really helpful if you could document the front panel of the code with what to do in order to see the problem you are seeing with the chart's width decreasing.
Thanks.

Stacked plots

Is there a way to have a stacked "Waveform Chart" with 8 stacked charts but display 16 plots, 2 on each chart?

Ok I found a way to do this. It is not exactly straight forward but the attached VI and control show what you want. The secret is in customizing the graph and using the "Y Scale Index" property.
Follow these steps and you should be golden.
1. Create your stacked plot with the 16 plots. So you will have 16 tiny little plot areas... no worries.
2. Take a look at the attached code and see how you can select the active plot and then the Y Scale Index associated.
You at the moment have 16 plots and 16 Y scales. Simple change the Y scale index of the last 8 plots to be 0-7.
3. Try that and notice you now 16 plot areas 8 plots with 2 plots on it, and then 8 that are empty.
4. The last thing is to get rid of the 8 "blanks".
5. Select the last 8 plots and make their Y scales not visible.
6. Finally right click on the chart and select customize.
7. Select window>> Show Parts Window. In that new window you can find the last 8 plots, and set their hieght to 1, and change their location. I suggest moving them under the top plot.
8. At this point you have a lot of free space. Select one of the remaining plots and increase its height to what looks good for just one plot area. Then select the 8 that you want to show and you can use the "Resize Objects" ring in the tool bar to make them all the same size. Move them to where you want and bingo.
9. You should now have 8 visible plots, and 8 that are hidden. Save the control and replace the one on your Front Panel.
You should be done. Let me know if or where you get lost because I know this is kinda strange.

How do you programmatically switch between a stack plot and an overlay plot with a waveform control?

One method i realize is to have two waveform controls, one visible and one not visible. The real issue here is, how to dynamically control the number of plots in a stacked plot. My case,
i will have between 2 and 8 channels. I have found that in the properties if i set the number of plots - Legend--Plots shown . I can control the number of stack plots, however, i must toggle from overlay to stack plots in design mode for the correct number of stack plots to be shown. Does anyone know a way around this problem or know of the property that has alluded me?

Hi,
You cant select between Stack plot and Overlay programmatically. Well not in LaBVIEW 5.1.1.
You could have two Charts, one set up for Overlay and the other setup for Stacked. Then hide the one you are not immediately using.

I accidentally deleted the download stack, but managed to get it back. How can I change back to stack view?

I accidentally deleted the download stack, but managed to get it back. How can I change back to stack view?

Right-click on the folder icon on the dock where you put it. Change it from 'Display As: Folder' to 'Display As: Stack'.
After that you'll be all set.

How do I change the number of plot areas in a Mixed Signal Graph

How do I *programatically* change the number of plot areas in a Mixed Signal Graph? I recognize that the developer can choose to add or remove a plot area during edit mode but I want to select between 2 or 3 visible plot areas and scale the plot areas appropriately. Is there a property that tells me how many plot areas (or yscales) there are? I also need a property that I can write to as to set the number of plot areas available.
Aside from manually making too many plot areas and then hiding the unneeded plot areas how can I do this?

Hello,
I don't think that is possible - I searched the property and invoke nodes but didn't find something to do that. This would make a great product suggestion though, which you can submit (it goes directly to R&D) by clicking the word feedback in the bottom left corner of the Contact NI page linked below:

Is this limitation by design? If we have a shared VHDX between two VMs, then I am not able to change the VM properties from SCVMM.

Hello,
that is a VMM issue.
If you did not deploy your virtual cluster from a VMM service template, VMM doesn't recognize the configuration.

Change the default stack size in the java.exe file

Does anyone know how to change the default stack size of the jvm?
I'm having problems with my stack. Is there anyway I can change it. I found a tool editbin.exe which is shipped with Visual c++, however I don't have the tool.
Thanks,
William

I am using JNI to connect java with a C++ application.
When calling the C++ appliction, STACK_OVERFLOW
happends. I tried java -Xss<size> to increase the
stack size, but failed.This has nothing to do with the above question.
Does anyone knows why?Probably because the java parameter specifies the java stack size and not the C++ stack size.

How do you create stacked plots?

Okay, I have tried for quite some time today to create a stacked plot, but without any success. I want to be able to put in a max and min range for the x-axis on the front panel. This x-axis will be used for three different y-axis. Each y-axis will have a different scale than the other ones. Also, each y-axis will have up to 6 different plots. I have attached an example of what I hope the final chart/graph/plot will look like. I have tried combining the x-axis values with the different y-axis values in an array (2D) and then plotting them but nothing seems to work right.

Never had much success getting what I consider "publication quality" graphs out of LV, but that is not what it was built for. It has a great looking GUI and the flexibility to get your data into a program to suit your needs. Doesn't mean that there aren't some features we'd like to see added, especially when it comes to axes and labelling. My advice to you is the following:
1. take a deep breath and decide if this is something you really want to do.
2. perhaps try an in-between solution like stripping down the plots and stacking three XY graphs on top of each other. You can programatically control the scales. You won't have overlap of the plots like you show, and all of the labels will be on the left.
3. Try a standard XY graph and fudge the labels using Ben's very elegant trick. Ben is the go-to-guy (IMO) for picture control questions
4. Explore the Picture VIs to generate plots piece-by-piece. You are in for a lot of work, but it is the only LV-only solution I know to get the results you are looking for. (Perhaps there are new and exciting features in LV2009 that someone will enlighten us with).
5. Do what I do. I use a MathLink connection to Mathematica when I need plots that I can't get easily in LV. You can retrieve the graphics object and display it in a container or a picture control. I use a picture control because the container seems to unload the image when I stop the VI. If you don't have Mathematica, or similar program, sorry.

How do you change the Number of Plots Shown property of a Waveform Chart at runtime?

Is there any possible way to change the Number of Plots Shown property
of a Waveform Chart at runtime? Thy Dynamic Stackplots example is
way to limited.....

There's a couple of ways to do this -
1. Manage the data going into the chart to only be what you want displayed
2. Use property nodes. Specifically, the Plot.Visible node. (LV 7 example attached).
