plot in node.js

Question

I would like to build a server using node.js which is able to plot graphs.

I could not find useful information so far on how to hook Matplotlib/ Pylab into node.

Maybe GNUPlot can be hooked up? I personally prefer Matplotlib but GNUPlot would be fine, too. In my experience the tools I mentioned outperform tools like flot or TheJit for huge data loads.

Any suggestions on creating fast plots from within node.js will be appreciated.

Answer 1

Either use child processes and execute external programs, watch for theit termination and take the output. Or have a look at the node-canvas lib if you want to do it by yourself.
