I think I am missing something with the new documentation because I can't find something simple. I am actively working at implementing a Gauge Chart and am employing the Ext.data.JsonStore (which the examples from ExtJS also use). But I can't seem to find the documentation for the JsonStore class.

Here is what I see when I go to the ExtJS 4 documentation:

URL I am looking at: http://docs.sencha.com/ext-js/4-0/#

Anybody want to tell me what I am missing?
