DPlot

David,

I have series of datapoints in a 2D plot. Is there a way to e.g give a dirent color to points whose values are less than a certain number. For example

All Y < a in Curve 1 should be colored Red (where a is a number )

Thanks

Sort of, though it isn't especially obvious.

First make a copy of your curve with Edit>Copy>Data Value & Edit Paste.

Then select Options>Bubble Plot. Select your original curve in the "Which curve?" box and the copy in the "Bubble amplitudes from" box. Select "Specify limits". Make sure "Use limit size and color" is selected, rather than "Don't draw bubble". For the min value enter a number slightly smaller than your a, for the max value enter a number slightly larger than a. Select a symbol type and the size of the symbols you want... and there ya go.
