i-Charts offers you the possibility to revert a photo of a diagram into a vectorial chart. You pick up a photo from your iPhone/iPad photo library, you adjust by zooming and panning the image to fit the screen (portrait or landscape). Than you can paint on the screen the shape of the diagram.
Once you're ready with you diagram you can shot with the "sight" tool as many points as you want in order to let the application know the original coordinates system
Finally you can maipulate you chart, edit parameters, change type of diagram, insert lables or delete it.
Display the charts, pand and zoom them!
