How to edit image axes in MATLAB to change direction?

The color image is built using the function imagebased on some information obtained using the function imread, and for the white and blue images I mainly select the coordinates of the heat point (mainly red and blue and their variations) from the map, and then display them using the function plot.

The problem is that the plotted values ​​are changing on the Y axis, and I cannot figure out how to change the Y axis of the graph to get the same correlation between the images.

Could you explain to me how to solve this problem?
