Problem with saving QChartView as vector image file

[Mohsin]

I using the QChartView to plot two-line series.Capture.jpg

To save this graph, I am using the following code. Although it works fine when I save it as a .png file. However, when I try to save it as .svg format it doesn't do anything.

Can anybody tell me what might be the issue?

QString path = QFileDialog::getSaveFileName(this, tr("Save as image"), "", tr("Image (*.svg *.png);;All Files (*.*);;"));
   if (path.isEmpty()) {
       qDebug() << "USER DID NOT SELECT the PATH!!!!!";
       return;
   }
   QImage img((chartView->size()), QImage::Format_ARGB32);
   QPainter painter;
   painter.begin(&img);
   chartView->render(&painter);
   painter.setRenderHint(QPainter::Antialiasing);
   painter.end();
   img.save(path);

QString path = QFileDialog::getSaveFileName(this, tr("Save as image"), "", tr("Image (*.svg *.png);;All Files (*.*);;"));
   if (path.isEmpty()) {
       qDebug() << "USER DID NOT SELECT the PATH!!!!!";
       return;
   }
   QImage img((chartView->size()), QImage::Format_ARGB32);
   QPainter painter;
   painter.begin(&img);
   chartView->render(&painter);
   painter.setRenderHint(QPainter::Antialiasing);
   painter.end();
   img.save(path);
