Hi All, I have used example 4 (http://www.ncl.ucar.edu/Applications/Scripts/conOncon_4.ncl) to shade a specific region. opt = True opt at gsnShadeFillType = "pattern" opt at gsnShadeLow = 17 plot2 = gsn_contour_shade(plot2, 0.05, 30, opt) How do I control size and density of the stipples in gsnShade? with regards -Deb
