View Full Version : Bubble type graph in extJS
1 Aug 2012, 3:40 AM
I am looking to implement a bubble type graph and a world graph , images attached. If not so can we implement something like that? Looking for examples.

These are custom charts .. so you would have to find one that you liked to create a wrapper, or perhaps use our Scatter chart as a basis to create your own.

Can you give some idea with code base , how can we manipulate Scattered Chart-Rendered?
Looking forward for your help..

This is just going to be an issue of trial an error. You have 3 completely different types of charts displayed.

Martin , thanks for reply.. I am more interested in first one, round shaped bubbles.
I am manipulating the graph but yet to find the right solution.

Have a look here: http://www.randelshofer.ch/treeviz/ for a Java example and I think the source is available.
Packing arbitrary circles within a larger circle is non-trivial...for a paper that includes an algorithm look here: http://www.sciencedirect.com/science/article/pii/S0925772102000998
Here's another reference...http://lip.sourceforge.net/ctreemap.html
You might want to start off with something a little simpler like a Circular Bubble Tree layout or a Radial Tree layout....they are easier to code up. See http://philogb.github.com/jit/
