Clear legend names in mixed signal plot

I want to clear a graph entirely and rewrite new data to the mixed signal graph. In order to clear it, I have to clear both the data and the plot names from the legend. I do not see an easy way of clearing the plot names...anybody know the trick here?

This works in L.V. 2012. It must be done BEFORE you reinitialize to default values otherwise you will get an error on setting ActPlot!! ...as the plots are no longer there! Works, but ugly. Any elegance out there?

Can i position my cursors in a mixed signal plot with my mouse?

i can move the cursor in the plot via the cursor controls with no problem. but it's a very slow and arduous process. i'd like to be able to just grab the cursor with the mouse and position it where i want to.
i can grab the cursor with my mouse now, but when i move it, it's like the cursor is locked to the position on the plot and moves the whole plot, which i don't want to do.
i just want to be able to position the cursor a little faster or quicker than with the left/right/up/down buttons that are avialable now. it would be great to be able to click my mouse at a point in the plot, and snap the cursor to it, or just grab the cursor and put it where i want to.
if anyone has any helpful suggestions or hints, i'd appreciate it.
i'm running labview 8.6 on vista and xp.
thanks for your help,

james and baji,
thanks for your input, but i guess i'm not very clear in my question. first of all i don't see a cursor locked property to use, so i'm a bit confused on that point.
but my problem is, i'm using a mixed signal plot, it has say three plots on it. the scales for the x is 1435 to 1455 while the y scale is 0 to 500. there are three plots displayed. using the cursor control buttons (the four diamond pattern controller for up, down, left right) i can position the cursor crosshairs at any point on the displayed plot window, whether on a plotted point or anywhere on the displayed scale.
but when i grab the cursor, and move it anywhere, i move the whole display along with the cursor, and all my scales change on the plot window accordingly to where i grab the cursor and move it. but the cursor stays locked onto that spot and the plot area moves. what i want to do is have the plot area stay where it is, and move the cursor only, not the whole plot..
what i'm trying to do is pick an xy coordinate with the cursor and write that point to a file. i can do that using the cursor control buttons, the cursor moves freely anywhere in the plot window, even though it takes a long time (holding the shift key speeds up the cursor).
unfortunately, i can't download any of the demo vi's you guys have left, my firewall won't let that happen.
thanks for your help though,

How do I add the channel-name to mixed signals?

Hello,
I want to save a XY-Signal to a tdm-File and import it into DIAdem.
So I merged the X- with the Y-Signal and connect the merged-signal to the "Write To Measurement File" VI.
In DIAdem I can see both signals but their name are "Untitled" and "Untitled 1". I don't know how to fix that.
If I use the low-level storage VIs, the other problem occures. I can give the X and Y-Channels my desired names, but they are in waveform - I want them as numeric channels in DIAdem.
So how can I give the mixed-signal the names
or
how can LabVIEW say to DIAdem that it is a numeric signal?

Hey Lukas,
To name your dynamic signals you can see this KB "How Do I Rename Signals in Dynamic Data?". After you name your signals appropriately, you could then merge them together and write to a tdm file. DIAdem will then be able to read the channel names from the tdm file. I hope this helps.

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

I have a customized mixed signal plot grpah and it when the plot names are written to it, it autosizes things and they are in chaos with overlapping text. Is there a way to fix this? I am also expereincing several labview crashes...

Mixed signal graph : Legend udate problem

When manipulating the graph in diagram window with properety nodes like example "Plot Visible", the legend of the mixed signal diagram will not be updated. Only when refreshing the front panel by scrolling with the mouse up or down, the legend is correcty updated.
How to refresh the front panel programmatically or any other solution ?
Thankx,
CLaude

Hello,
Thank you for posting to the NI Discussion Forums. I was unable to reproduce this problem with LabVIEW 8.0.1.
Perhaps this was a problem fixed in the release, or perhaps there is
something different about our two computers (such as OS for
example). Check out this page to update your version of LabVIEW 8. Please let me know if this fixes the problem.

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.

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.

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.

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:

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.

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.

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.
Attachments:
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,
