Set NEW data for histogramReturn to overview

This code

QCPBars *amp=new QCPBars(ui->hist->xAxis,ui->hist->yAxis);
.......
amp->setData(x,y);
hist->replot();
hist->update();

only adds new data to the histogram and doesn't clear old data. Moreover, I call this method every time new data is needed.
How to clear the histogram every time?
hist->clearGraphs(); doesn't work

The problem was solved by global object designation QCPBars!
