Library inclusion problem

[santosh_kumar]

Help needed to know the reason for below errors. These errors which are in color red are result of a library inclusion( .a).

Above errors are resolved by adding libCorePlot-CocoaTouch.a library under the targets.
Now the problem is control is not coming to code blocks other than constructScatterPlot. Any suggestion would be appreciated.

Thanks,

Proper inclusion of CPLayerHostingView instance and adding graph to that instance solved the problems.

Thanks,
