DPlot

This macro crashes on LineType[n,1] when the graph has fewer than n lines. Color[n, x,x,x] keeps going without crash. Suggestion?

Whoa, now! I cause enough crashes without calling a legitimate error message a crash!

It bothers me a bit that Color and LineType aren't consistent and I'll likely change this. In the meantime you can get around the error message by setting the maximum number of curves to the largest curve index you'll use in your macro. (Double click on the Max Size area of the status bar).

Sorry to have overstated the severity of the problem. My work-around is to Redraw after the error message.

2.3.1.6 fixed this problem. Thanks.
