how to add zoom control to linechart

[Rafael Campaña]

Hello,

I would know if it's possible to add control to a LineChart. Control
like zoom in and zoom out, select an area over the chart and zoom it,
etc.

Where can I found the source code of the LineChart?

Greeting and thank you, Rafael.

The new chart controls wrapper (http://code.google.com/apis/chart/interactive/docs/gallery/controls.html) might do what you want.  You can also use data views with the setRows() method to set your minimum and maximum x-axis values.

As far as the source code goes, if I recall correctly, the visualizations API is not open source.

Thank for the answer,

but I was looking for for the maner to add some kind of region
selection and zoom in over it.

But I haven't found the way to add an event listener when you click
over the axes plane.

Something like this region selector?

(drag the handles on the area chart at the bottom to select a different region affecting the map on the top).
