1. What’s Plotr?

Plotr is a javascript charting engine for use with the PrototypeJS Ajax Library. It uses (simulated) Canvas to draw Bar/Line/Pie charts in most modern browsers.

2. Who wrote Plotr?

Bas Weneker is the creator of Plotr. He came on the idea while he was looking for a charting engine for Prototype. Then he saw Plotkit, a js charting engine for the Mochikit Ajax library. He used Plotkit as an example for Plotr, but after a while there was almost nothing left of the old Plotkit.

3.Where can I download Plotr?

You can download Plotr on the Plotr Project page.

4. What about the development version?

You can get the latest development version form the Google Project Hosting SVN. Just point your SVN client to http://plotr.googlecode.com/svn/trunk/. To build and pack your own version of Plotr, take a look at this article: ‘Automating builds with Ant’.

5. Which browsers are supported?

Supported browsers are: Firefox 1.5+, Safari 2.0+, Opera 9.0+ and IE6+.

6. Is Plotr licensed?

Yes, it’s released under the New BSD license.

7. Where can I find documentation?

I’m more like a coder, not a writer. That’s the reason there’s a lack of documentation for Plotr. To learn how Plotr works, I recommend to download Plotr, and take a look in the ‘example’ folder. For each type of chart there’s an example.

8. Does Plotr support negative values?

No.
