Seemed great as long as I tried simple graphs. However when trying the style em3d for 3dgraphs I got stuck. Now splot seems to want 3 datalines followed by a blank line before next 3 datalines. Tried things as providing a datafile instead of array as workaround but failed. In gnuplot splot 'file' matrix with em3d doesn't require blank lines but I found no way to put more parameters than style for 3dgraphs, so stuck again. If it's only possible to use a small subset of gnuplots features I rather find some free java chart package instead.
Very useful. Thanks.
Works, very small, no complaints.
