Hi, Could someone tell me how to change the style of selected lines in a contour plot to dashed, dotted, chain-dashed etc. I would like to make a simple two-dimensional contour plot with dashed lines for negative values, and solid lines for positive values, with no color (just black on white). I can use dx to create contour plots with colored solid lines, but cannot figure out how to change the style of selected as is possible in NCAR graphics or gnuplot. Thanks. -george carnevale
