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 (http://www.wysota.eu.org/).

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