I'm trying to plot a chart with axis labels of different colors for positive and negative values, the effect is shown in the image below. Is there any way to achieve it? Thank you.

I don't think you can do that with basic QValueAxis, but you could customize the appearance of custom ticks using QCategoryAxis, you only need to explicitly set the tick range. – musicamante Aug 27 '23 at 13:12

Thank you! This is indeed a workaround, and I'll try it in some charts with fixed axes. But it is so troublesome for axes with dynamic range. – PX.Liu Aug 28 '23 at 09:02

You need to rebuild the axis labels whenever the range changes. Just connect to the related signals of QValueAxis. – musicamante Aug 28 '23 at 10:57
