how to set absolute positions of axis in core plot

Question

Hi, I'm working with core plot on iPhone now, and I'm trying to set up the ScatterPlot graph in such a way that [0,0] coordinates are always at the same place (that is 40 pixels from the left and 40 pixels from the bottom)

I just wasted 4 hours trying to get this to work, and still have no idea, help!

Bonus question - how to set up axises to make only the >0 parts visible?

Answer 1

graph.plotAreaFrame.paddingBottom = 40.0;
graph.plotAreaFrame.paddingLeft = 40.0;

Bonus: Setting the padding will move the axes and plot area so your origin is offset from the left and bottom by 40px.
