Hi-
As a new IDL user, I'm just beginning my trek up the learning curve.
My first trials are plots I know how to do in other plotting packages
and I'm having trouble getting IDL to do things that are easy in the
other packages (principally MONGO). Since I expect that this is my
limitation, I thought I'd ask some people who know.
My first trial is to plot vectors (or rays, to avoid using vector in
a non-IDL fashion) representing nuclear reaction fluxes. Essentially I
have 4 arrays, X, Y coordinates of the end point, angle and ray length.
Using the plot and arrow commands, I've managed to write a little
procedure which does the basic ploting, but I have 2 problems.
First, I can't figure out how to make the X and Y axes have the same
unit length, so that, for example a 45 deg angle is actually 45 degrees
on the display, not simply a slope of 1.
Second, the arrow command seems not to honor the clipping of the plot
routine, so it plots arrows in the margins.
Any suggestions on solutions to these problems, or sources to research
solutions, are appreciated.
