Emprise JavaScript Charting with Canvas

Category: Canvas, JavaScript, Library

Jacob Miller and his team have created a rich charting library called EJSChart.

EJSChart is canvas-based with many interactive features such as zooming and auto scaling. The product has been in development for some time but the web site has just been established.

It features interactivity, axis scaling, zooming, scrolling, ajax-driven data, and much more.

Impressive! And about the license ?

Comment by Nard — April 10, 2007

Maybe its a stupid question..

Can I get the chart in a image format like jpg?

I saw other canvas based chart components, but i didn’t find the way to get the charts in jpg.

Thank’s in advance and sorry for my english!

+1 on license. Open Source? Commercial?

Apparently it does not work on Internet Explorer 7. Everything looks OK except for the graphics that are not displayed.

I went to their site and Windows Live OneCare detected a trojan called JS/Xilos.

Looks pretty neat. I couldn’t figure out how to zoom back out. The tooltips on data points are a nice touch though.

I have had a lot of success with:

It doesn’t cover absolutely everything, but it has been easy enough to extend it.

ie6 is the ‘enterprise’ browser. proably installed on 90% of enterprise PCs., and it doesnt have canvas, so cant run this Enterprise charting class?

maybe enterprise charting class should use divs and transparent GIFs to achieve its magic..

Nice one ! But crashed my firefox when I got into higher zoom level … Well, maybe it’s just my PC

To answer a few questions:

– It will be a commercial product but licensing and pricing has not yet been finalized.

– Zoom out by dragging up and to the left, or double clicking

– There are currently no static image output options.

– There is no canvas in IE 6 or 7, both are supported via Google’s ExplorerCanvas implementation (i.e. vml).

Is there likely to be a free “personal” or “non-commercial” license at any stage?

Comment by Justin Carter — April 11, 2007

It’s buggy on my Opera… But forgetting about that, it’s pretty cool.
