Q3DBars problem

Modify bars examples when using Q3DBars

M_yearAxis - > setRange (0, 6);

M_monthAxis - > setRange (0, 100);

The static float tempOulu [6] [100];

At this point, the interface has become a long and narrow channel mode, but the annotation has become messy, the vertical part cannot be lowered a little, can the translation also seem to be unable to achieve this, what should I do, I have not found a solution?

I want to modify what happens to the steps of m_yearAxis, m_monthAxis.

Make my interface more beautiful
