This is already possible with the setScaleRatio method of the QCPAxis class.

Here is a basic example:

QCPAxis *x = qcp->axis(QCPAxis::atBottom);
QCPAxis *y = qcp->axis(QCPAxis::atLeft);
y->setScaleRatio(x, 1.0);
replot();

If you want to keep the aspect ratio when the size of the QCP widget is changed, then you have to override the resizeEvent method.
