Sure. For example this wiki example works fine. http://www.jsoftware.com/jwiki/Studio/Plot#A3DFunctionPlot The only changes required are in the last line. The reason they are required is that the jengine doesn't include wd & gl2 functionality, so you need to specify to output to pdf (note that jconsole in j602 has the same issue). The jpdf command that ships with jhs is just a cover for the plot command that forces the output to be pdf rather than gl2 or gtk for Linux. gamma=: !@<: real=: {...@+. x=: steps _3.5 4.5 40 y=: steps _1 1 40 z=: real gamma x j./ y dat=: _3 >. 12 <.
