Can I change the axis range of the QChart

[unionRd]

QValueAxis *axisX = new QValueAxis;
axisX->setRange(0, 8000);
axisX->setLabelFormat("%g");

I can change the range in the program,Can I change it in the widget in run time?

Can I change it in the widget in run time?

Some thing like this, widget some where in GUI and set value there and give it to axis ? then yes, you can change the range in the run time. USe QSpinBox / equivalent widget and pass the vale of the QSpinBox / equivalent widget using the signal and slot.

See the Surface Example under Axis ranges for studying the graph.

Hope this helps.
