DPlot

Hi David,
I have a graph with X Axis of type Date and Time, I want to put a second axis (on the top), with the time from start, starting from 0 ending with the number of actual minutes. I 'm not sure that there is a way to do it!

how to use Elapsed time format?

________

First you need the numeric form of the initial X. Switch to the default number format for the X axis and use the Scan data button to get that value. Call it T0 for our purposes. The equation for the top X axis would then be A=-T0*24 and B=24.

Perfect
