[Gnuplot-info] pm3d interpolate fails

[hlitz <hei...@gm...>]

Hi,

I want to plot a 3d plot using pm3d with interpolation. I am running gnuplot
4.2. I
have scattered input data but used dgrid3d to define all points.

set pm3d
splot "input.dat" using 1:2:3

works showing a colored plot. However

set pm3d interpolate 1,1
splot "input.dat" using 1:2:3

just plots points with no pm3d at all.

Maybe the parameters to interpolate are wrong what does steps in scan stand
for?

My x and y axis ranges from 0 to 9 my z data from 0.85 to 0.92.

thanks for your help!
