Hi, i have a problem plotting a 3d data file. It has 3 columns, X Y Z, when i try to plot it with lines, it just draws lines joining the points and i want some kind of mesh. When i order the points it justs draws horizontal lines and not squares (when data are ordered, gnuplot for example gives me the right output), like this http://t16web.lanl.gov/Kawano/gnuplot/datafile-e.html  (at the end of the page).
And if it's possible, can it be filled with a colour?
I tried doing plot 3d '*.dat' with surface
the problem is that pyxplot draws some kind of waves, and not the right lines joining the data points

Thanks in advance
David
