Replace RGraph with a FLOSS JavaScript charting library

[sebastianbergmann]

PHP_CodeCoverage currently uses (and bundles) RGraph to render the charts of the code coverage dashboard in the HTML code coverage report. It has been brought to my attention that the license of RGraph is not compatible with the BSD-style licence that PHP_CodeCoverage uses.

I think that Highcharts can be a great replace. It's under the Creative Commons Attribution-NonCommercial 3.0 License for non-profit projects.

Highcharts looks very nice.
Additionaly it seems that highcharts can be driven with JSON while rgraph has an oop api.

So I'm preferring highcharts here too.

• jquery based
• dual licensed MIT/GPL2
• used by Piwik

But i guess Sebastian is looking for s.o. to implement the graphs, not advocating fashionable plotting libs :-)

I eat JS for breakfast. Which lib you prefer? Do you simply want to replace RGraph while keeping all the features?

[sebastianbergmann]

I want to keep the features while replacing RGraph with Highcharts or whatever. Thanks! :-)

Ok sweet. I'll look at the code and fork when ready to implement. I'll use Highcharts as it seems to be approved by many in this thread. Please assign the ticket to me.

+1 to Highcharts. I used it recently for http://github.com/elazar/ledger-stats and got very positive feedback.

Thanks to everyone who wanted to help!
