How can I plot over long time, from 1 to 24 hours, and width servral channels in one graph

[lars-olov]

I have try to get a plot over long time, 1 to 24 hours and more than 2 channels, up to 6 channels in same graph. What I have try is to use a xy plot and then by  letting the x axis min max be controlled, see picture, the thing is you can only use 2 channels to data on a xy plot, if I those a chart plot, when i use the same structure to control the max min for time span, no lines are plotted for some reason, see picture.

Regards // Thanks

You can put as many XY plots on one XY graph as you like, there should be an example for multi-plot XY (dont have LV infront on me right now).  you can build up in an array the X and Y values and periodically regraph them.  Change the X scal as you wish or just replot a subset of each XY plot.
