Chart X Dimension Value Change

[jpo]

Hi

My application allows the user to change the number of input channels that a chart displays during runtime. When the number of channels vary the X Scale range values reset to zero for the chart. Is there a way I can stop this?

I have include a simple demo program showing this issue. When the var number of channels is changed the X scale of Variable Channel Chart is reset.

Thanks John

This isn't completely correct, but it doesn't clear the history: ChartDemo_1.vi

Thanks for the insight. In my version, I display multiple points per channel per loop. Application records 120 channels at 2048 samp/sec so display every point is not possible. When I wire up the output of the array subset vi which is a 2 dimensional array, it will give me an error. Is there a work around?

Do you know why this does this happens?

Thanks John

One suggestion (if it's purely UI related) would be to move to LV2011 and display the visibility checkboxes.
