For future reference, this feature has now been addressed in Core Plot issue #156. As of 0.9 it has not been merged however a diff is available at http://code.google.com/p/core-plot/issues/detail?id=156

Core Plot only draws straight line segments between your data points. You can insert extra points between your existing data, but you have to calculate the values yourself to get the desired curve. If you insert enough points, it will appear to be a smooth curve.

CPScatterPlot *Cps = [[[CPScatterPlot alloc] initWithFrame:graph.defaultPlotSpace.bounds]autorelease];
Cps.identifier = @" ";
Cps.dataLineStyle.lineWidth = 1.0f; // if u want smooth the line 
//Cps.dataLineStyle.lineColor = [CPColor blueColor]; // if u want color the line 
Cps.dataSource = self;
[graph addPlot:Cps];
