#2793 Example in "Complex values" section doesn't work as presented in text

[Anonymous]

Page http://gnuplot.info/docs_6.0/loc1215.html contains following code example

     set palette model HSV start 0.3 defined (0 0 1 1, 1 1 1 1)
     set cbrange [-pi:pi]
     set cbtics ("-π" -pi, "π" pi)
     set pm3d corners2color c1
     E0(z) = exp(-z)/z
     I = {0,1}
     splot '++' using 1:2:(abs(E0(x+I*y))):(arg(E0(x+I*y))) with pm3d

that must result in that graph, but with default labels
, however actual graph looks way different (see attachment)
