Reversing order of the y-axis in Google Sheet line graph

I have a simple line graph with Google sheets that looks to show the league position trend for multiple teams on a weekly basis.

The X-axis reflects each ‘Gameweek’ whilst the y-axis shows the possible league position. I want the Y-axis to start with the lowest league position as the vaue at the bottom left with the highest at the top left but it’s currently reversed.

I have looked at all Graph settings and I just cannot figure out how to reverse the Y-axis.

Any ideas?
