graph x axis problem

[JimJones]

Is it possible to get the x axis to be independent of the graph, by this i mean i have a graph generator that varies in speed but i want the x axis which is real time not to be affected by the varing speeds of the graph generator.

[altenbach]

I cannot quite understand what "...varing speeds of the graph generator..." could possibly mean. Can you attach a simple example?

In an nutshell:

1. If your x-values are not equally spaced, you should use an xy-graph.
2. If your x-values are equally spaced, you use a regular waveform graph or chart.
