using QwtPlotMultiBarChart

[ginu s. <sam...@gm...>]

Hello,
      I am trying to use QwtPlotMultiBarChart in Qt Widgets application.
Tried putting the following code in MainWindow.

MainWindow::MainWindow(QWidget *parent)

    : QMainWindow(parent)

{

    setMinimumSize(500,500);

        QwtPlotMultiBarChart *barChart = new QwtPlotMultiBarChart();

    QVector <qreal> v1 = { 12.0, 15.6 };

    QVector< QVector<double> > result;

    result.push_back(v1);

    barChart->setSamples(result);


    barChart->setStyle(QwtPlotMultiBarChart::Grouped);


}


But the application is crashing.

*Do i need to do something else to support the creation of of Bar chart.*


The .pro is changed to link to qwt as follows:

win32:INCLUDEPATH += "C:\Apps\Tech Dev\References\Qwt\include"

win32:LIBS += "C:\Apps\Tech Dev\References\Qwt\v140\qwt.lib"
