how to hide the scale in qwt plot

[babu198649]

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.

#include <QtGui>
 
#include "qwt_plot.h"
#include "qwt_plot_curve.h"
 
int main(int argc, char *argv[])
{
	QApplication a(argc, argv);
 
	QwtPlot *plot=new QwtPlot();
 
	QwtPlotCurve *c = new QwtPlotCurve();
	c->attach(plot);
	c->setPen(QPen(Qt::blue));
	double x[1000], y[1000];
	for (int i=0; i<1000; i++)
	{
		if (i<100 && i>10)y [i]=1;
		else
		y[i]=0;
 
		x[i]=i;
	}
	c->setData(x,y,1000);
        plot->axisWidget(QwtPlot::yLeft)->hide(); //this does not work
	plot->show();
 
	return a.exec();
}

#include <QtGui>

#include "qwt_plot.h"
#include "qwt_plot_curve.h"

int main(int argc, char *argv[])
{
	QApplication a(argc, argv);

	QwtPlot *plot=new QwtPlot();

	QwtPlotCurve *c = new QwtPlotCurve();
	c->attach(plot);
	c->setPen(QPen(Qt::blue));
	double x[1000], y[1000];
	for (int i=0; i<1000; i++)
	{
		if (i<100 && i>10)y [i]=1;
		else
		y[i]=0;
		
		x[i]=i;
	}
	c->setData(x,y,1000);
        plot->axisWidget(QwtPlot::yLeft)->hide(); //this does not work
	plot->show();

	return a.exec();
}

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.
