Re: Zoom in Choosel Visual Data Exploration Framework

[Lars Grammel]

Hi Guillaume,

I needed to add some required functionality for zoom+pan to
Protovis-GWT. You would need to check out protovis-gwt from svn (
http://code.google.com/p/choosel/source/checkout ) to get the version
that supports pan+zoom properly. An example of pan+zoom with
protovis-gwt can be found at:

Cheers,

Lars

Hi Guillaume,

I added a sunburst visualization with pan + zoom to the protovis-gwt examples:

http://web.uvic.ca/~lgrammel/blog/protovis-gwt/index.html

The code is in SVN.

To get colors per subcategory, you might want to look at the
BubbleChart example, which does something similar:

.fillStyle(new JsFunction<PVColor>() {
public PVColor f(JsArgs args) {
PVDomNode d = args.getObject();
return category20.fcolor(d.<ClassData>
nodeObject().packageName);
}
}

Hope that helps,

Lars
