I know one way which is not very straight forward:
plot3d([cos(x)*sin(y), sin(x)*sin(y), cos(y)],
[x,-%pi,%pi],[y,0,%pi],['grid,20,10],[plot_format,openmath]);
You then click on the upper left corner to get the menu and click on
Config. Change the values of xradius and yradius to 1.5 and then click
OK. Go back to the menu and click on Replot.
The current CVS version (soon to become Maxima 5.10) provides a more direct
access to "Config" and "Replot". Perhaps we should modify plot3d to allow for
xradius and yradius options for plot3d when openmath is used.
