Please give me a way to code a method to convert cartesian coord. into java/picture coord. system I'm not supposed to use predefined functions like affine, scale(), transform, etc for this method.
Heres the picture: http://i45.tinypic.com/2z4fgog.jpg
For eg. i want to plot a point on java system from cartesian coordinates: (0.905, 0.360) & (-0.023, 0.410)
I need write the code inside the method: coordinateToPixel()
