Displayed Data


Greetings,
If/when I zoom in on my displayed data, can I obtain the max and min values of the data that are being displayed. 

For example, let's sat that I have
(latitude, longitude)->(altitude) projected in 2D with altitude is depicted as RGB. If I zoom in (shift+left click), am I able to get the "ranges" of the visible domain values? I.e. 
x1 < lat < y1
x2 < lon < y2
I thought that I could do this with the DataRenderer getRanges() method. Would this be correct? If so, is there a way to get the default DataRender from the DisplayImpl, or do I created one and add it to the Display? 

Thanks for the help!!

-kevin.
