Hi Thomas,
if you _really_ want ease of use you should probably go for Openoffice
Calc. However, I agree with Roberto that you should go for gnuplot.
Google for a starting tutorial, there should be several around, and then
install 'gnuplot-doc', the excellent documentation which comes with
gnuplot. You will have more of learning curve, but the results are worth
it. Also, you get to avoid these horrid pseudo-3d graphs excel-style
which have a 3d look but present simple 2d data. The only area where I
found gnuplot lacking is for the display of unstructured data (i.e.
finite element meshes) - which is not what you wanted to do anyway.
Hth,
