Set graphics views coordinate system centered bottom-left instead of top-left

I have created a Graphicsview and noticed that the coordinate system looks like this:

(0,0) (1,1) - - - - - - - (n,n)
(1,1)
  |
  |
  |
  |
(n,n)

However, what I would like to have is the following system:

(n,n)
  |
  |
  |
  |
(1,1)
(0,0) (1,1) - - - - - - - (n,n)

Is it possible to shift the coordinate system to be like this in a neat way?

Solution

  • Ok. I figured this one out!

    Using self.scale(1, -1) will mirror the graphicsview around the y-axis.

    Similarly, using self.scale(-1, 1) would mirror the graphicsview around the x-axis.
