Touching a graph with a finger while another finger is down causes a large jump

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a graph with user interaction enabled
2. Place one finger on your screen
3. Place a second finger down on the other side of the screen

What is the expected output? What do you see instead?

I would expect nothing to happen as this should be the start of the pinch 
gesture, but instead it seems to think the second finger is the first one which 
moves across the screen very quickly and hence the large shift

What version of the product are you using? On what operating system?
Sorry how do I find out the version of core-plot?

iPhone - iOS4

Please provide any additional information below.
The fix I have for this so far on iOS4 is as follows:

-(BOOL)plotSpace:(CPPlotSpace *)space
shouldHandlePointingDeviceDraggedEvent:(id)event atPoint:
(CGPoint)point
{
UIEvent *evt = (UIEvent*)event;
if ([[event allTouches] count] > 1) {
    return NO;

}
//your code here
}

Has anyone observed this issue on recent devices and/or iOS versions? I suspect 
it has been fixed by better gesture support in the newer versions of iOS.
