Combination of Stacked & Overlaid Waveform Chart

[StoneTrees]

Hey everyone,

I've got a challenge for you that would really help me out.  I'd like to use - specifically - a waveform chart to display four parameters overlaid on two divisions (in stacked mode) i.e. two parameters plotted on the first division and two parameters plotted on the second division with no additional divisions possible.  I have an example attached that gets me halfway there (written in version 8.2), but I can't seem to figure out how to make the waveform chart display only two divisions instead of the four dictated by the bundle tool.  I suspect this isn't possible as I can't seem to find a property that allows me to control the number of divisions displayed but hoped that someone else might know a trick or two to disable those pesky additional (and blank) plot fields.

Thanks in advance for any help!

Hey Ronin,

I took a look at your example, and I also had no luck getting those windows to disappear.  A possible work around would be to just use two different charts, and plot two signals on each chart.  Is there a reason you may not be able to go that route?

Have a great weekend!

Using multiple charts is my fallback solution and the way I handled this on the prior version of my LabVIEW tool.  Unfortunately, the tool is a major CPU hog as it handles many parameters (up to 100) at a relatively high rate (25 samples per second) for long periods of time (up to six hours).  My hope was that by condensing this down into a single waveform chart, the inherent efficiencies baked into LabVIEW might be able gain some CPU.

Thanks for taking the time to look at it.  I'm currently experimenting with using a picture control as I've heard that may net me a CPU gain as well.  Though, I suspect I might be revinventing the wheel.

Cheers,

Andrew

Here you go....

there should be enough here to get you what you need.

Thanks for finding this option!.  I tinkered with it a bit but got kind of goofed up right near the last few steps.  I'll play with it some more and see if I can things straightened out.

Cheers!

I believe the drawback I ran into was that the cursor was not available on the control so i ended up going witht he Mixed signal graph, which still had a draw back that you cannot have the cursor exend thru all the plot areas and ONLY snap to one trace.

Another way to do it: play with plot area size and color. See the attachment.
