如何从QChart显式设置刻度标签？

Question

I have to create a chart and use QChart . So I looked at the QChart dynamic spline example (because I'm going to create a dynamic chart), and I found something strange there.

Below is the launch screen. The code is the example code provided by Qt, except for setTickCount() .

I changed the value of tick from 5 to 10. I thought that if I changed it to 10, it would appear as 0, 1, 2, 3, 4, ..., 10 as the scale value. But it does not.

When moving by the scale interval, I think that it should be increased only by the scale interval exactly. What should I do? The code looks fine.

You might want to try calling void QValueAxis::applyNiceNumbers() , somewhere in the constructor. Take a look at void QValueAxis::applyNiceNumbers() in Qt documentation.
