use charts libary that allows commercial use instead of highcharts.js

[LilithWittmann]

I know highcharts.js is really cool but doesn't allow commercial use in the cost-free version. The highcharts.js license faq says:

IF I AM USING THE SOFTWARE ON A COMMERCIAL COMPANY'S INTRANET, DOES IT REQUIRE A LICENSE
Yes. The Developers License allows you to install and use the software on commercial company's intranet.

So every company that wants to use airflow has to pay 390$ for a highchart developer license?
Maybe it would be an option to replace highcharts with chart.js or d3.js?

I would recommend http://metricsgraphicsjs.org/ for this. The mozilla license is a bit more favorable.

It looks like Highchart's definition of "non-commercial" isn't what I though it was. I'm not even sure it's in line with the creative commons specs. We also might be able to get a blessing from them, though it might just be easier to rip it out.

I've used this lib before: http://nvd3.org/

Ok I will try to replace highcharts with one of these libraries (and maybe refactor the javascript part a bit ;-) )

[mistercrunch]

Oh wow! that is ambitious. Sorry about my javascript :)

[LilithWittmann]

Ok, I (re)implemented some of the chart types:

• line
• bar (grouped, stacked)
• column (grouped, stacked)
• stacked area (stacked, stream, expanded)

but I have no idea how to implement the others (esp. heatmap and parallel coordinates) with nvd3 /o
You can find my branch here: https://github.com/LilithWittmann/airflow/tree/new_chart_libary

Nice!

Parallel coordinate is one of those d3 examples, the license looks ok there. For heatmap we can probably just remove the feature.

Now there's a few views in the application itself (landing times and duration charts). The Gantt chart might be a git more tricky but it isn't too hard to reproduce while hacking a line chart. I'm hoping I can get to this sometime next week.

I pulled the branch and opened a dozen of charts on my end and only a few actually worked. I'll have to dig in and do some work to make this work.

d3 implementation is underway also as requirement to do apache releases.
