Qwt Plot: Hide axis

[cherple]

I'm trying to hide the axis of my Qwt Plot widget. I did the following:
QwtPlot::enableAxis(xBottom, false);
QwtPlot::enableAxis(yLeft, false);

The bottom axis disappears nicely, and although my left axis disappears as well, my plot become squished. My plot used to be in a square, but after removing my left axis it becomes squished into a thin horizontal bar. I searched online but everyone's saying to use enableAxis, but why is my plot being squished? And how do I overcome this? I only want to remove the axis without my plot changing its shape.

Thanks.
