QCustomplot

[Harshavardhan]

Hello,Iam a beginner in qt.Please help me in coming out of linking issues of QCustomPlot with Qt 5.1.0

The issues are with
QPrinter printer(QPrinter::ScreenResolution);
printer.setOutputFileName(fileName);
printer.setOutputFormat(QPrinter::PdfFormat);
printer.setFullPage(true);
printer.setColorMode(QPrinter::Color);

You can check the issue in the below attached png file.
Any one suggest me which plotting library should i use for plotting sinewave in qt.

Thank you in advance
