question about threshold of f-measure

Thank you for sharing this cool toolkit.
I have a question about threshold of the f-measure plotting code.

After the np.flip operatoin, the fg_w_thrs becomes [ >= 255, >= 254, ..... ,>=0].

When saving the curve data into np file for ploting , thess lines flip the fm data again.( so now fm should be [0, 1, ...., 255])

But when plotting image, the x axis(threshold) here starts from 1 to 0. I guess this should be from 0 to 1.
