Xy graph multi plots
Hello,
I have a need to plot a curve on an X-Y graph which is Voltage (Vsd) vs Current (Isd). After the first plot, I need to set another voltage (Vg) to a new level and repeat the plot. I would like to do this without erasing the original plot so I can generate a family of curves. Currently, I am using one trace on the graph which traces to zero at the beginning of the next plot. I need to create an entirely new plot on the graph instead of the original going to zero at the beginning of each plot. I cannot plot all curves at the same time because the voltage (Vg) level will change with each curve. Any suggestions will be appreciated.
Thanks,
Mark
Maybe I misunderstand the question...
Multiple plots on the XY-graph, means you need to put them in an array. If you don't have all the graphs at once, then you could simply build the array dynamically. I.e. you put the array in a shift register, and add elements (measurements) to it as you go.
See the attached vi for an example.

Express XY Graph Multi-plot Cursor point
Hi,
In mixed signal graph >> Property >> Cursors Tab >> Enable Allow dragging here if we select Multi-plot, it will show X scale and all Y-scale value in Cursor legend.
How can I get these same options in Express XY Graph?
Sivaraj M.S
CLDYou need to use a property node and find the curser position and then plot those points in a seperate xy plot (only it will be one point instead of an array). You will still have to plot it as an array of one point.

Mixed Graph - Multi Plot Cursor Problem
If I plot both Analog Waveform and Digital Waveform in a single Mixed Graph, and when I choose watch all plots in cursor legend, LabVIEW crashes with an error message.....
I have also attached the Print screen image of that Error

I found a solution to overcome that error.
Build all the array data at first and then generate digtal waveform in single instance.
ie., With number of numerical array data, build a 2D array of numerical data and make a transpose and then generate a waveform.
It generates number of digital waveform equal to that of the column size of 2D Array.
Do not build generated digital waveforms. This creates an error while using multi plot cursor--> watch--> All plots.
I have attached the modified, error free Vi with this message for your reference.

Hi,
I'm experiencing a problem using a multi-plot xy graph. I have to display 2 plots together, and make them appear and disappear many times during the program running.
But when I close LV and restart it, the second plot (plot1) doesn't appear, and also I lose all the properties I've set for it (name, color,...). If I don't shut down LV everything works well.
What can I do?Stefano Moret wrote:
When you write about use property nodes, I'm using the "visible" one.
Your suggestion is to try also to set all the properties from there? Maybe it's a good idea, I'll try.
Here are some code snippets I used once to initialize the graph and later on change legend entries depending on user selection.
You can also change the way plots are represented during run time. You always have to start with ActPlot do selct one of the plots.
Good luck -
XY graph multi plot live points and colour control
Hi All,
I'm trying to do something that should be simple but is proving to be difficult so far. I have had a good look through previous topics and found things similar but not actually what I want.
In my experiment I scan intensity vs wavelength.
Ideally I want to be able to:
1) run a scan and see the points plotted live.
2) Then I want the plot to stay on the graph when I run the next scan, etc.
3) I'd like to do an arbitrary number of scans. e.g. To initiate a scan I press a button, an arbitrary number of times.
4) I want to make it so that the current scan is plotted live in one colour (red), and all the previous scans remain plotted in another colour (blue).
5) Sometimes I may want to clear the graph of all scans and begin again, without having to stop the VI.
Items 1-3 can be taken care of easily by placing the Build XY graph and XY graph object inside the for loop that runs the scan, and unticking 'Clear data on each call' in the propertes of Build graph. See first attached VI.
However, at the beginning of a scan it joins the last point of the previous scan to the first point of the next scan.
The difficult parts are 4 and 5.
For item 4 you need to build an array of plots, which is easy if you know the number of plots, but here the number is arbitrary. So how do I do that? I've had a go by trying to use Insert Array in different ways but I haven't worked it out. Then hopefully using the XY graph property nodes I can set the colours of the plots.
For part 5 it is not enough just to use the invoke node = reinitialize to default, and have a button that executes the node. This clears the graph but then when you run the next scan all the previous plots pop up again, indicating that the array that stores the plots is not actually cleared. The second attachment shows how I'm clearing the graph.
My biggest problem is item 4, and combining item 4 and 5 together.
Please help.
Solved!

Current method_Items 1-3.vi 18 KB
Item 5 idea_with no item 4.vi 18 KBThe key is understanding the data type. If you hover over the graph's terminal, you will see that multiple plots are simply an array of single plots. Once you know that, something like this quick modification is fairly easy to come up with. I also added events to make it more readable. Note that this isn't actually a good way of doing things (for instance, you can't abort the drawing in the middle), but it shows the graph concept. You might wish to look at some code like producer/consumer designs.
As for the colors, you're right that the properties can help you there. I will leave it to you to figure out the exact properties, but when you start a new plot, you will basically want to reset all the others to white and make the new one red.

Multi plot graph - auxiliary curves
I am in trouble with a multi plot graph. There is a wave chart that I have to plot an auxiliary line when the user clicks on the graphic. I know how to get the initial point and the final point of the auxiliar line. But I don´t know how can I plot this line in the same graph.
Any ideas, sugestions or examples?
Thank you in advanceSpeaking only for myself, I am not sure about the nature of your request.
Could you please post some code showing an example of what you can do now and a jpg of what you desire.

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.

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,
DarrenDarren:
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.

I am using an XY graph with 5 curves which belong to one of two y axes each. All curves share the same array of x values. I do not like the cursor legend so I want to read out the values of the one cursor programmatically. I can create a multi-plot cursor which watches all the 5 curves but I cannot find how I can read out the 5 corresponding y values of my cursor. Any help?
Thanks,
LX (using LV2014)Use the cursor index property value and wire that to an index array function for each y array.

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 KBHello,
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,

Cannot draw logarithmic graph in Plot Multi-XY vi
Hello All,
I'm trying to use the Plot Multi-XY vi in the picture controls to dynamically draw an X-Y grid on a picture control. I need the grid to be logarithmically scaled, but when I check the "x log?" and "y log" booleans in the cartesian axis attributes to True, nothing at all shows up in the picture. If I un-check those options, I get a nice linear grid. Any help would be greatly appreciated!
Thanks,
JasonHi Ravens Fan,
Here's the VI (taken from an NI Example with just the Cartesian Axis Attributes added and the x and y logs turned to true. If you switch them to false you get a nice graph, but when set to true nothing shows up at all.
Thanks,
Jason

XY Multi Plot Log.vi 15 KB -
Dear All,
I am working on Mixed Signal Graph with Multi plot cursor.
My target is to move the cursor on X axis time scale and get the y axis values of all the plots.
i got some ex. on forum but i am facing a typical problem explained as follows:
By chaning the cursor plot i am getting the y axis values for each plot.
The problem is that the values are continuously changing of the plot y axis value automatically, ans also the values of the respective plot does'nt match all the time, it changes.
I have attached a example, in that the values of the respective plot changes every time.
Am i missing anything, please guide.

Shrek

Hi,
I really like the look of the graph used in XY Multi Plot.VI
Does anyone know if you can have two scales on the y-axis for this type of plot? How to implement it?
Thanks
aleks.Yes, you can have two Y axes. You right click on the one you have and choose "Duplicate Scale" to get the second scale. You can then choose to "Swap Sides" if you want it on the other side of the graph. From the Plot Legend, you can click on a plot to choose which Y scale will be used for that plot. You might also want to play with grid colors or something like that to get some visual clue which plot goes with which scale.
