I have several (up to 8 or 10 ish) series of data, and they all need to be plotted on a graph. This is easy.

The hard part is that each individual data point has its own timestamp. So for example, rather than having 8 values at 1s, 8 at 2s, 8 at 3s and so on, I’ve got series 1 point 1 at 0.34s, series 2 point 1 at 0.58s and so on.

Is this actually a scatter graph? I need to draw lines on the same chart and compare trends over actual elapsed time. Y values would need their own scale because the series range from 0-3000 to 0-1.2

Yup, plot as scatter. You can still plot series, but it’ll be a darn sight simpler that way.

For a bonus point configure Excel so that double clicking on an Excel graph rescales the graph to zoom in on that point by a factor of 2 and right clicking on a point zooms out by a factor of 2.

Ooh.. sounds useful, ta.

I can send you some code to do the double click to zoom in bit, it’s quite simple to set up in VBA…..

sounds like functionality they should have built in in the first place…

but back to the OP, yes, scatter plot, time as the X axis. if you correctly apply a date/time format to the column it should even get the axis labelling right.
