I'm trying to find a perl module that will help me make a certain kind of
graph. I believe it's called a time-series graph, but I'm not sure. It's a
graph of how two variables behave over time. You can see a couple examples
at:
http://www.trendmacro.com/a/goodman/keyIndicators/pvCharting.asp
and
http://www.thestreet.com/comment/openbook/1332231.html
I have tried using gnuplot and the GD package for these graphs, but have
been unable to get either one to generate reasonable looking graphs. I
believe it's because the data that I'm graphing is not strictly described
by any function since some X value can have multiple Y values (just at
different times).
Has anyone had success in graphing this kind of data? Can you recommend a
module or some documentation or pointers that may help me out?
Looking forward to any help you can give me!
