Re: Problem with griddata and contourplot

[Walter White]

No, the data is scattered 3d points, that are results of a FEM calculation but are no 
longer in triangular form.

Do yo know what causes the error, is there some sort of limit in gnuplot,
as the triangulation using griddata runs fine and my program quits during
contourf...

if your data is defined on a triangular or tetrahedral mesh,
you might want to use the 'fpl' package to export it to vtk format
and then view it with paraview.
