[visualization-api] Use specific datable rows or columns to draw a visualization

[Renato Beserra]

Is it possible to ignore some rows or columns of a datatable in some visualization? I have a set of data which is presented as a table, and a subset of this data should be presented as a chart.

I had to create two different data tables to achieve this behavior. Is it possible to present the subset as a chart without creating a new dataTable?

Thanks.

Absolutely, use a DataView ( http://code.google.com/apis/chart/interactive/docs/reference.html#DataView).  You can use DataTable#getFilteredRows to restrict your rows by whatever criteria you choose and then pass the returned indices to DataView#setRows.  DataView#setColumns allows you to choose which columns to include in the view.  When drawing the chart, pass the DataView object instead of the DataTable to the draw call.

Thank you very much. This is exactly what I need!
