Line in scatterplot shows beyond points with linear interpolation

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a CPTScatterPlot and set the interpolation to 
CPTScatterPlotInterpolationLinear
2.
3.

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

See the attached screenshot, when there is a sharp maximum or minimum, the 
orange line goes a few pixels past a blue dot before going to the next blue dot.

What version of the product are you using? On what operating system?

iOS 6

Please provide any additional information below.

I don't see this with a stepped or curved interpolation.

Forgot to add, this is with the CorePlot release 2.0 branch.

This is caused by the line style used for the data line. You need to adjust the 
lineJoin and/or miterLimit to eliminate the sharp corners. The Mac version of 
CPTTestApp demonstrates this.
