Thomas,

You could click on the image and then drag one of the 'handles' to make the
image larger.

But a better method is to use the ImageSize option in the plot so that the
image is produced in the desired size to begin with.

<< "Graphics`"

SphericalPlot3D[Abs[SphericalHarmonicY[3, 0, the, phi]]^2, {the, 0, Pi},
{phi, 0, 2*Pi}, PlotPoints -> 50, PlotRange -> All, ImageSize -> 250];

Also, with BoxRatios -> Automatic, the default option, the plot is very high
and narrow. Such plots are always somewhat difficult to show, and
Mathematica often has a difficult time with them. You could change the
BoxRatios but then that distorts the shape of the surface.

Also, if you could parametrize the surface in terms of the and phi and then
use ParametricPlot3D you could probably obtain a more efficient plot with
easier control.

Hi,

I use mathematica versin 5.0
I try a visualisation of spherical Harmonics:

<< Graphics`
SphericalPlot3D[(Abs[SphericalHarmonicY[3, 0, the, phi]])^2 ,
{the, 0, Pi}, {phi, 0, 2Pi},
PlotPoints ->  50, PlotRange ->  All];

I get a very small figure.
How can I get a bigger output?

Many Thanks
Thomas Rausch
