So I’m working on a project written in C which serves up various information as HTML webpages. I’d like to include various types of graphs (bar graphs, histograms, what have you). Thus, I would like a library of C functions (C++ is OK also) which allow me to do some setting up of parameters, then passing in various data points, and then presto, I get out HTML source text for a chart or graph, which I can then serve on up to the end users.
Anyone have any ideas or recommendations?
thanks
There is gnuplot. I’ve never looked at the code, but I have played with it a bit. I wrote a visualization package in Perl based on GD::Graph. It is a two pass process - the first takes data from pretty much anywhere, like a spreadsheet, and translates it into a standard form. This is the customized part. The second, driven by a GUI, plots a variety of graphs. I’m in the process of debugging a new capability that allows you to normalize based on things like the number of parts shipped. This is web based. gnuplot isn’t.
I think I’ll give that a try, thanks.
