Chart Widget

[wirasto]

If they are not so complicated it's not such a big deal to create a custom, own widget for that, using the paint event for drawing...

You could also have a look at Charts for Qt4.

I get sample from http://www.wysota.eu.org/charts.html. I tried for add to my Dialog. But i always get crash.

ColumnChartView *cv=new ColumnChartView(this);
...
....
ui->myLayout->addWidget(cv);

ColumnChartView *cv=new ColumnChartView(this);
...
....
ui->myLayout->addWidget(cv);

To copy to clipboard, switch view to plain text mode 

ColumnChartView inherit from QAbstractItemView. And can't add to Dialog like a Widget ?
