Dynamic graph plotting with C++ and MFC

Question

I'm working on a C++ MFC apps for windows that gather information from different sensors and plots them dynamically in a chart.

My goal is to update this app.

it currently uses this http://www.codeproject.com/Articles/425/A-2D-data-visualisation-class as a 2D graph plotter. The problem is that this source is really old and I was wondering if some foss/opensource 2D graph ploting library was better.

I've seen some paid ones (chart director/gigasoft charting library) for example. The only foss one I found was gnuplot. But as I understand, gnuplot is mainly for producing fixed plot and doesn't provide allow interraction on the plot itself.

If you have any pointer on the subject I would be very glad.

Answer 1

There aren't any good, up to date and free ones in 2012. The few on CodeProject are the only ones, but as you already known they're all old. I maintain my own controls that do just what I need them to. A bit of work, but still the least painful way.

Answer 2

I have this one bookmarked in codeproject, though I have never really used it. It looks good, and claims to be "high speed".
