I have a graphical representation problem to solve, and my graphics
literacy is nearly nothing, so I'm hoping somebody here can tell me what
tool I want for this.
Imagine an X-Y graph, where the two vertices of the graph may be of
varying length. We want to be able to plug in a set of numbers x (the
length of the X axis), y (length of the Y axis), a (a number of
equidistantly-spaced points along X) and b (a number of similar points
along Y). Output should be a set of lines drawn perpendicular to each
axis for each point along that axis; the axes should not be printed in
the final output, only the lines.
Up to now my friend has been drawing all those lines by hand in a vector
drawing tool on a Mac, and I'm sure there has to be a much simpler way
to generate patterns like that.
Once we have the output, we need to be able to save it in some sort of
reasonably portable graphics format to be overlaid on maps, and crop the
images to cover irregular spaces. We have that part solved, it's just
getting all the nice lines drawn without doing it manually that has us
stumped.
I'm pretty sure Red Hat comes with two or three ways to do this but
nothing occurs to me as obvious. I'm sure the GIMP could do this, but
I'm a GIMP weakling and don't know where to start. I tried looking at
xfig and gnuplot, but without some examples to work from I'm swimming.
So, if anybody does stuff like this, I'd love to know where to get a leg
up.
Thanks,
