DPlot

I note that performing a Generate "Y = f(X, Y1, Y2, ...)" based on another curve, produces a new curve not with a new point for every X in the existing curve, but with a new point for every X with interval dX. If the original curve had X values that were not equally spaced, the new curve will have a different number of points. In certain cases, such as performing further processing, this is far from ideal. For example, if your source data is CSV with shared X values, performing a generate suddenly produces a more complicated XYXY data set where the X values are not shared.

Is it possible to produce a new curve that only has points that correspond to the points in the original curves?

In the dialog box for "y=f(x, y1, y2,...)", there is a box to check, "Use X values from curve" and then a selector for the curve number that you want to match points with.

That's a relatively new capability within the last year I think. The current paid version 2.3.0.7 has that capability. Maybe it doesn't exist in the trial version?

Ah huh! Thanks jsc, I have 2.2.8.3 and the option doesn't exist. A simple matter of upgrading!

Thanks, Jon. Your next suggestion automatically goes to the top of the list

Glad I could help!
