how to change between 2/24 hour display?

[Rhayes]

I have a waveform chart, right now it only displays data for 2 hours, I'd like to give the user the ability to display between 2 and 24 hours.

I altered the chart history length and I tried to set the x range min and max values. What I got was the graph displaying two windows that never scroll to keep up with current point, how can I change between the latest 2 hour data and 24 hour data?

btw I'm using 4.0

If you want to display either the LAST 24 hour data or the LAST 2 hour's, what you only have to do is to change the Xscale min value between 0 and (Xscale max value - n), where n is the number of points to be displayed in the 2h window. Do not modify the max value.
Works fine in LV7. Hope it will work in 4 !
