I posted it not because it is in the web, but because it is powerful. For example: automatic extraction of barplots of selected color.

Before I explored tons of applications requiring to manually click of the every single point. And actually I am hoping for an app automatically getting scales and coordinate system.

Automatic extraction of scales and coordinate systems is a much harder problem (http://xkcd.com/1425/).
