How to save QChart as image?

Question

I have chart with differrent series. I need to save current ChartView as image. I tried to do it as:

QPixmap p(this->size());
QImage* image= new QImage;
QPainter *painter= new QPainter(this);
chartView->render(painter);
if(!image->save("test.png"))
    qDebug()<<"ERROR";

I have next error: "QPainter::begin: Paint device returned engine == 0, type: 1"

you can use grab and save functions

grap image and than save it

chartWidget.grab().save("test2.png")
