Change direction of the Y-axis for a single figure

I have the following code:

figure();
% BLACK CURVE plot
open_jpg = imread('fig_01_JPG.jpg');
image(open_jpg);
axis equal
xlim([90 190]);
ylim([210 320]);
set(gca, 'YDir','normal')

hold on
% BLUE CURVE plot
Im = imread('fig_01_JPG.jpg');
CoordinateMatrix = pic2points(Im);
scatter(CoordinateMatrix (:,1), CoordinateMatrix (:,2),'.');
% ax = gca;
% ax.YDir = 'reverse'
% set(gca, 'YDir','normal')
hold off

I would like to change ONLY the direction of the Y axis of the figure with the black curve so that it overlaps exactly with the blue curve of the other figure.

I tried using the "reverse" or "normal" command but it only applies it to the global figure.

% ax = gca;
% ax.YDir = 'reverse'
% set(gca, 'YDir','normal')

What you need is to rotate, try imrotate

I actually have to invert the image with the black curve (in this case flip along the x-axis) so that the image with the black curve is equal to the blue curve. By rotating the image with the black curve I do not get the desired result :)

Have you tried

maxV = max(CoordinateMatrix (:,2));
scatter(CoordinateMatrix (:,1), maxV - CoordinateMatrix (:,2),'.');

This may work.
