Delete Plot Area in Mixed Signal Graph

Hi,
I would like to delete not needed graphs and groups in Mixed Signal Graph but I see when I right click on the graps the Delete Plot Area is disabled and grayed. Could you please let me know how can I delete plots and groups in MIxed Signal Graph.
Thanks

Sorry, too snarky.

Errors with multi-plot cursors on Mixed Signal graphs

Using a Mixed Signal graph, it seems that a multi-plot cursor does not snap correctly if XScale.Multiplier is not set to 1 - it seems to ignore it altogether. A single-plot cursor on the same graph does not have this problem. Am I missing something?
In the attached VI, XScale.Multipler = 0.1, and Cursor 1 (Single-Plot) shows the correct value, but Cursor 2 (Multi-plot) does not.

MixedSignalCursor.vi ‏14 KB

Hello,
The behavior I see is that the multi-plot cursor which is snapped to plot 0 seems to generally follow an "imaginary plot" which corresponds to a scaled version of plot 0, where the scale factor is the value wired to the XScale.Multiplier property. I don't think this is desired behavior so I have filed a corrective action request to R&D to have this addressed. I am sorry for the inconvenience - hopefully you can live with an X-scale multiplier of 1, or the single plot cursors for the time being. It also takes the offset property similarly, offsetting the "imaginary plot" by whatever value is set there.
In any event, if this poses a significant problem with additional contingencies, please let me know and I'll be sure to include any updated information in the corrective action request!
Thank you,

LabVIEW 8.6.1 did not fix glaring Mixed Signal Graph bug :(

I'm pretty dissapointed that NI has JUST NOW released 8.6.1 (more than 6-months after releasing the buggiest LabVIEW version, ever). The Mixed Signal Graph bug still exists and is very annoying. The visual bug occures when you add more than 1 plot on a mixed signal graph and then try to resize the legend. The Y-Axis labels do not move appropriatly. You really can't resize the legend with this bug.
Where can I find a list of known bugs in LabVIEW and verify that this is in that list? How can I add weight to this bug report so that NI will address it for the LabVIEW release? How can I express to NI that I don't want LabVIEW 9 until they can fix all the problems in v8?

Not sure about the "buggiest version", v2.5 had its share. Had to save your work every 1/2 hr. or risk loosing everything when you got the almost guaranteed "insane error" which always seemed to occure when you had done the most editing since your last save.

The OP obviously never had to work withLabVIEW versions prior to 5.1.
And while 8.6 had a few nagging bugs including visual ones it is actually quite stable and good. No comparison with 8.0 for instance or even 8.0.1

You just did! But unless you are a site with several 1000 LabVIEW licenses you will not outweigth those other customers who do have that many licenses and do want more features as soon as possible rather than an annoying graph display bug getting fixed.

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?
Jonathan

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:

Mixed Signal Graph Legend Plot Name and Graph Area Y Scale Name hidden

Does anyone know why the mixed signal graph stops allowing traces to be drag'ed and dropped between different plot areas?

I have a mixed signal graph that allows me to drag and drop my traces between the plot areas, then it stops allowing it.
If I start with a new graph it allows it but eventually stops allowing it.
I have 4 XY charts feeding the one mixed singal graph through a bundle function, then I run it once and drag my traces to the correct plot area
and hope that it keeps working.

1:30 Seconds ARRRGHHH!!!! I want my popcorn NOW! Isn't there anything faster than a microwave!

Hi Tim,
That sounds like some interesting behavior. Can you reproduce what you were seeing, or have you continued to be able to drag the signals to other plots since you saved and reopened your program?

Mixed Signal Graph: Cursor Position Property for Multi-Plot Cursor

I'm working 6 waveforms on 3 different plot areas in a mixed signal graph in LV2009. When I try to pull the Cursor.PosY property from my cursor (in which Watch All Plots is True, and is set to Multi-Plot in the graph properties), it returns the value of only the first plot in the cluster of waveforms fed into the graph. I've tried changing the active plot, active plot area, nothing changes. I am able to retrieve each value via the cursor legend, but I cannot pull each of those values into another portion of my program. Also, I noticed that when setting events in an event structure, any events relating to a cursor drag aren't present as they are in a waveform graph. My workaround is to create an indicator for the Cursor.PosX property and monitor when that value changes, but I feel there should be an easier way. Any help is appreciated.
Thank you in advance!

Jeanius,
I am not quite sure why the cursor pos in the Wavegraph reference does not change when you change the active plot, but if you grab a reference to the specific cursor and then change the active plot things you receive the expected behavior.

LabVIEW crashes when you run a VI that contains a mixed signal graph with a multi-plot cursor.

Hello, LV 8.2.1 notes indicates the following bug fix:
43SAIR2A Fixed an issue where LabVIEW crashes when you run a VI that contains a mixed signal graph with a multi-plot cursor.
I am running this version, and still have this behavior. Is there anything I may be missing, and/or certain circumstances that may still be causing this?
thanks in advance,
Darren

Darren:
I looked at the CAR ID that you mentioned and the issue has been resolved in LabVIEW 8.2.1. To verify something similar, I ran the attached VI and things worked just fine. Please feel free to send me the steps to follow to reproduce the issue you are running into in 8.2.1.

How do I configure the mixed signal graph property node to set the plot names

I have a mixed signal graph displaying digital and analog data in two groups.
I would like to programmatically set the names of individual plots i.e. rather that the digital graph displaying 'Digital 0->Line 0' I would like to set it to 'Signal 1' in the vi.
How do I do this?
Probably via the property node but I cant get this to work without errors? (i.e. i cant find the right combination of node arguments to set.)
Also, I can set the names of the plots of the component waveforms programmatically, but when I bundle the plots together to form the mixed signal graph, the plot names are reset to the mixed signal graph default values. Can this behaviour be turned off?

What are you doing? You need to select the plot first and then set the name, like this:

Mixed signal graph with mulitple plots

Hello,
I am using a mixed signal graph in a DAQ program to display
the data from multiple channels after I'm done logging. The data is in a 2-D array and I'm bundling
it with a x0 and Δx just like a waveform graph.
Each row in the array has the data from each channel and I want each one
to be displayed in a separate plot area.
I know I can set each plot to a different y-scale using the properties
of the graph, or using the plot legend, but I'm using this in a sub vi and
would like this to happen automatically when it runs. I'll never have more than four channels so I've
made four plot areas, but it always just sticks all the data in the first plot
area. So how can I set up a property
node for the mixed signal graph to make this work? I attached the code I'm using for the bundle and graph.
Thanks
Doug

mixed signal graph code.png ‏5 KB

After working at this a little longer I was able to solve the problem. I just had to figure out which properties to control. The active plot and the y scale index nodes set each channel to a different plot. The picture shows how I set up the property nodes. The blue wire is the number of channels that I was using and the strings are the channel and cursor names. I know there's probably a better way to do this but I'm not a software engineer, and the guess and check method of programing has worked for me so far.

Stacked Bar Plots in Mixed Signal Graph

Is there a way to have a stacked bar plot compiled and displayed in the mixed signal graph indicator from multiple plots as inputs?

I think we are getting closer but I do not see what I would expect in a stacked bar graph in excel. Please take a look at the data in the array in column 525. It has more than just qty 2 of the value 1 in many of its cells. Hence I would expect to see a spike greater than 2 which is what I see on the chart that you provided. I did the task in excel and it was easy to do and have attached it for your reference. It is the same data that I provided above in the prior vi.

How do I size teh group area oin teh mixed signal graph to fit my signal names?

I have a simple mixed signal graph and I have programmed my signal names and they are longer than the width of the existing group pane on the object and I want them to be visible. How can I resize the graph panes after I write the names to the object? I know I can customize the thing, but is there a method or property that I am missing here?

It looks like this is a known problem. You can change the legend size using a property node for waveform graphs and charts, but not for a mixed signal graph. A good work around would be to mouse-over the grey bar between the legend and the plot area until your cursor changes to the resize tool. You can then size it to be large enough to show the whole legend. This is an issue that is set to be resolved in future versions of LabVIEW.

XY Scatter Plot on Mixed Signal Graph

Anyway to accomplish this without being exceedingly clever? Seems that all the data type options require evenly spaced X values. I really like the Mixed Signal Graph because of all the options it gives the user at runtime. Thanks!

How to change the size of a mixed signal graph programmaticaly and properly ?

Hello to all
I'm posting because I can't find a way to do the following thing :
I want to resize a MixedSignal Graph programmatically using property node which are in read/write mode.
For XY graph it works nicely using PlotAreaSize (? not sure of translation) (Zone de tracé : taille : hauteur;Zone de tracé : taille : largeur in french).
For subpanel it works nicely using ContainerBounds (? not sure of translation) (Limites du conteneur : hauteur Limites du conteneur : largeur in french)
For Mixed signal graph I use PlotAreaSize. It changes perfectly the width according to the change in size but not the height. Apparently the height of the plotArea is changing but not the height of the teminal....
You have to pan in order to see the whole graph...
That is not what i'm expecting, does anybody know a way to change effectively the height of a mixed signal graph ?
(Please avoid the answer like : "choose an other thing for plotting" thanks )
Thanks for any help !

Hello,
And thank you for posting here.
Indeed PlotAreaSize does not work as hope.
You could take a look on this link :

It is one of way to do what you want.
