toScreenPoint result is off #367

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I'm adding a touch slider on a graph chart, using toRealpoint and toScreenpoint 
to convert coordinate system. It worked fine if the the Renderer.setXAxisMin 
and Renderer.setXAxisMax are set to the first and last points in the data 
collection.

But if I set min and max to other value to get some zoom in and out effects, 
the slider position will be off. I called GraphicalView.repaint(). Is this an 
achartengine bug or do I need to do something to update the internal 
properties? 

What version of the product binary library are you using?
I tried 1.2.0 and 1.1.0

Is the "slider" using other scale than 0?

No, I'm not using other scales. I saw APIs with scale argument, but I'm not 
using them.
