[Tioga-users] Gridlines

[David MacMahon]

Is there an easy way to put grid lines on a plot?  By easy, I mean an  
existing method I can call with perhaps a few options like line style  
and color.

If not, I guess I'll have to write one myself that gets the axis  
information and the plot boundaries and then draws the grid lines  
individually.  Does anyone have any tips on how to do that?  How  
would I get minor tick locations?
