Axis in 3D Data Visualization is quite inconvenient
Unsolved
Qt for Python

 The length of Y axis is half of other two axis, and it can't be modified, I can't understand what the point is in doing that.
 The interval of grids/labels is unequal, if we use it to visualize some structures or geometry, different proportions of XYZ will mislead us about the shape of the object. And there is also no straightforward way to set the interval value. But isn't the main purpose of Q3DScatter/Q3DSurface to visualize shapes?
 We normally use the vertical direction as the zaxis, but here Yaxis instead.

This is actually 8 vertices of a cube, but it looks like a cuboid.
