Version 4.4.3 and 4.6.0 4.4.3 just returns the "i"s, 4.6.0 returns a warning Warning: empty z range [0:0], adjusting to [-1:1] and a table like this: # Surface 0 of 1 surfaces # Curve title: "ffile binary filetype=png" # IsoCurve 0, 3871488 points # x y z type 0 1703 0 i 1 1703 0 i 2 1703 0 i 3 1703 0 i ... The third column (not present in 4.4) only contains zeroes. So maybe splot ffile binary filetype=png with rgbimage is not the correct plotting command. So which command did you use? Best wishes, Ingo
