I have to place 4 spines on the same chart with different Y ratios, so I need to set up 4 Y-axes.
I have read the "muti-axis" demo from QT creator, it shows a example of two Y-axis and the two Y-axis are put on left and right side.
It's good when there is only two spines, but when I have 4 spines, how to relocate the 4 Y axis? Is it possible to place the 4 Y-axis at the tick point of X-axis? like the image below.
