Dear Monks, I have to create about 200 graphics from a perl script that look like this: * 100 datapoints in a black line * 20 datapoints using a red line and having 5percent errorbars round them... * The output format is PNG (or gif, but, please, w/o LZW) I can do that using gnuplot and two files but that takes a long time (esp. since the PNG support seems to be buggy: gnuplot becomes >50MB in memory and needs more than 17 minutes for the job) I already have all the data in a hash of arrays: $data{$number_of_graphic}0...120 and ask you if you know of any tips how to fasten things with perl regards Stefan K
