xfig plot image 'xfig_plot_image'
% Example 1: logscale variable x = [PI:10*PI:#100]; variable y = [PI:5*PI:#80]; variable IMG = sin(x) # transpose(cos(y)); variable xf = xfig_plot_image( IMG, x*180/PI, y*180/PI; padx=0.025, pady=0.025, dx=-.5, xlog, ylog, fill=20 ); xf.render("/tmp/test.pdf");
% Example 2: image of Example 1 but with gaps variable tmp = [[1:30],[35:65],[75:115]]; variable x = struct{ lo = tmp/11.5*PI, hi = (tmp+1)/11.5*PI }; tmp = [[1:40],[50:90]]; variable y = struct{ lo = tmp/18.*PI, hi = (tmp+1)/18.*PI }; variable IMG = sin(x.lo) # transpose(cos(y.lo)); variable xf = xfig_plot_image( IMG, x, y ; cmap="drywet"); xf.render("/tmp/test.pdf");
