    Default how to hide the scale in qwt plot

    hi

    i want to hide the y-axis(QwtPlot::yLeft) in the qwt plot how to do it .

    how to hide y-axis in the following program.


    Qt Code:
    1. #include <QtGui>
    2.  
    3. #include "qwt_plot.h"
    4. #include "qwt_plot_curve.h"
    5.  
    6. int main(int argc, char *argv[])
    7. {
    8. QApplication a(argc, argv);
    9.  
    10. QwtPlot *plot=new QwtPlot();
    11.  
    12. c->attach(plot);
    13. c->setPen(QPen(Qt::blue));
    14. double x[1000], y[1000];
    15. for (int i=0; i<1000; i++)
    16. {
    17. if (i<100 && i>10)y [i]=1;
    18. else
    19. y[i]=0;
    20.  
    21. x[i]=i;
    22. }
    23. c->setData(x,y,1000);
    24. plot->axisWidget(QwtPlot::yLeft)->hide(); //this does not work
    25. plot->show();
    26.  
    27. return a.exec();
    28. }
    To copy to clipboard, switch view to plain text mode 


    in the 25 th line i have tried to get the scale widget and tried to hide it even the it is not successful.

    Qt Code:
    1. axisWidget(QwtPlot::yLeft)->hide();
    To copy to clipboard, switch view to plain text mode
