st: Dashed lines indistinguishable on graph

[Lance Gravlee <lanceg@umich.edu>]

Statalisters,

I have a line graph to illustrate an interaction effect between two 
continuous variables.  The color version looks fine, but the lines on 
the graph are indistinguishable when the graph is displayed in a 
grayscale scheme (e.g., s2mono, sj) -- all three appear as solid lines. 
 Note that the legend properly displays three different line styles.

For an example, see http://www-personal.umich.edu/~lanceg/linemono.png

Have others had this problem?  What's the solution?

Thanks for your help.
