Rails Library for Generating Graphs and Charts

Rails
1

Hello Friends,

Hope all are doing well.

I was seeking some guidance on open-source, stable, efficient and
better library (plugin/gem) for generating chars and graphs in rails.

here i am looking for graphs/charts with multiple scale in a single
axis. also i am having concerns for exporting charts in some of report
like pdf or image etc.

Please let me your thoughts/experience/guidance on this.

Thanks,
Piyush.

Use gruff charts or google charts…
Gruff Charts: http://nubyonrails.com/pages/gruff
google charts: http://blog.brijeshshah.com/google-chart-4-rails-gc4r/

This plugins helps you generating charts in form of images…

Or, the free Open Flash Chart, which uses Flash to render charts, just
like
google’s does:

http://teethgrinder.co.uk/open-flash-chart/

And, ofcourse, someone already developed a plug-in for RoR:

http://pullmonkey.com/projects/open_flash_chart

But none of these 3 chart ‘components’ allow the user to ‘zoom in’ and
‘scroll’ the view… I’m still searching for something like this.
Preferably, it would request ‘JSON’ / ‘XML’ data real-time as the user
scrolls to or zooms to regions of the chart… Or did I not read the
Google
Chart API docs that well?

Nope. Google’s charts are straight images, so they are generally the
better choice. There is usually little reason to force Flash on your
users for something this simple.

Indeed they are, images, I saw that too. But you will not be able to
generate these charts when a user is not online, would you? Or, not able
to
connect to google (like in a very strict intranet environment :wink: )

if you want the charts to be ‘interactive’, though, (like zooming and
scrolling around the data real-time) Flash is not that bad. I admit, I
hate
to use it too, but OpenFlashChart is the only open source component I
could
find that delivers almost all this functionality without requiring a
connection to some other website…

No, of course Google Charts won’t do anything if Google’s chart service
can’t be reached.

How about the visualization components from the SIMILE project (
http://simile.mit.edu )? The ones such as Timeplot are pure DHTML/JS,
and they don’t rely on external services as far as I know. There seem
to be some projects aimed at using these with Rails, but I don’t know
how well they work.

But you are wrong. Open Flash Chart is free.

Open Flash chart works like a charm, just disable all ‘animations’ and
your
client will take you seriously :wink:

I have used it for a prototype application with Symfony (yes, I know,
PHP…) but for the ‘real’ application I’m setting everything up with
Rails.
