How can I flip scatterplot on its y axis AND flip whtiespace too?

Hi there I have some tracking data that I have plotted on a scatter plot (top photo) but I would like to flip it on its y axis. I have tried this with the following command:

y_values = min(y_values(:))+ max(y_values(:))-y_values (shown in the bottom photo) however this does not als0 flip the white spaces belpw the points in the original image. Any suggestion on how I can achieve this?

Thanks

It is not clear why you do not just

set(gca, 'YDir', 'reverse')

??
