Hi,
I am using the SURFACE procedure to define the axes. I want to plot a
unit sphere, and an array of data points. I am faced with two issues,
which although are not stopping me from going ahead with my task, are
important if I have to make the plot look neat.
1) Like the ISOTROPIC keyword for PLOT command, is there a
corresponding command for SURFACE that would force equal scaling for
all the 3 axes? This is really necessary, because otherwise the sphere
of unit radius extends well beyond 1.0 along at least 2 axes at a
time. More importantly, is it just an issue with the scaling, or am I
missing something here.
2) I have the array Vsph0[3,251001] for the sphere and I am using
following command to draw it:
plots, Vsph0, psym=3, /t3d
I earlier tried using the SHADE_SURF command. However, instead of a
smooth sphere, I get a figure which looks like a distorted trumpet.
I would appreciate any help in solving any or both of the problems
given above.
Anand.
