Delete a scale?

[xl600]

I have a VI with a stacked chart.  How to I remove the third chart from this?  The "Delete" option is always greyed out on the Y scales.  Is there some trick here?

Thanks,

Not sure why this worked, but after changing the number of plots to 2, then un-stacking and re-stacking seemed to display the correct number of plots.

It depends, I think, on what you wire in. So only wire in the plots you want. You can use the split signals, merge signals and select signals vi's to manipulate the signals going into the VI. Take a look at those VIs and see if you can figure it out from there.

I wouldn't have guessed to do that, but it works like a charm.  Seems like a usability issue in the stacking paradigm.

Thanks!

I wire in anywhere from 1 to 256 signals into the chart (Within a tab control containing 10 stacked charts).  Tab 1 has '1 stack', 2 has 2, etc.. The stacks represent the number of unique scales discovered amongst the plot sources.  It's all based on the MultiPlot Master library so the stacks are actually static.  MM only provides a 3 stack through 10 stack variation so I was trying to get a 1 and 2 variation to support smaller numbers of scales.  It's all terribly complicated and my VI was a disaster until I re-wrote it as a JKI state machine.
