Get set of visible rows after filter

[xman]

After I filter the grid how do I get the set of filtered rows that are visible.  I want to update a chart with the set of visible rows in the grid.

Likewise, when they clear the filter how would I get the set of visible rows?

Do you have examples and do you recommend how to bind your grid to a chart, that is, what chart product should I use?

[paramvir]

filtered rows can be directly obtained from dataModel.data

$grid.pqGrid("option", "dataModel.data");

You can use Raphael or any other good chart library. http://g.raphaeljs.com/

Example of pqGrid integration with Charts: http://paramquery.com/pro/demos/charts_inline
