What is your preferred way to produce charts in a

Question

I'd like to add some pie, bar and scatter charts to my Ruby on Rails web application. I want want them to be atractive, easy to add and not introduce much overhead.

What charting solution would you recommend?
What are its drawbacks (requires Javascript, Flash, expensive, etc)?

Answer 1

The gchartrb gem is no longer maintained, it seems. The author points to these gems:

• googlecharts
• gchart (seems abandoned as well)

Answer 2

ChartDirector. Ugly API, but good, server-side image results. Self contained binary.

Answer 3

If you don't need images, and can settle on requiring JavaScript, you could try a client-side solution like the jQuery plugin flot.

Answer 4

Morris.js is nice and open source. I would like to choose it comparing to highcharts. There is a new great video tutorial from Railscasts

Answer 5

I am a fan of Gruff Graphs, but Google Charts is also good if you don't mind relying on an external server.

Answer 6

The new Google Visualization appears to produce charts that are of more varied type, better looking and interactive than Google Graphs.
