You can get the axis interval from your QwtPlot object:

Code:

---

double width = this->axisInterval(QwtPlot::xBottom).width();

---

or you can get the width of the canvas like this:

Code:

---

int width = this->canvas()->width();

---

Thank you for your response, but are those two widths equals?
