Accepted Answer. You can change the direction of increasing values along the y-axis by setting the YDir property of the Axes object. If you want the values to increase from bottom to top (2-D view), then set the value to 'normal'. Alternatively, if you want the values to decrease from bottom to top, then set the value to 'reverse'.In MATLAB, I want to reverse my x-axis, but I dont actually want to reverse the image/graph when doing this.

We can increase the distance between the y-label and the y-axis in the following way: plot(A, B); y=ylabel('xxx', 'rot', 0); % do not rotate the y label. set(y, 'position', get(y,'position')-[0.1,0,0 ...

For example, if X values range from -10 and 10 and Y values range from -5 to 5, you should pass extent=(-10,10,-5,5) to imshow(). Rather than mirroring the image vertically, it mirrors the axis marks. While not an answer the question it can be an alternative in some cases. In addition it remaps the axis to a new range instead of the …

Alternatively, we could use the following code to reverse the x-axis: #define x and y. x = [1, 4, 8, 11, 13, 14] #create scatterplot of x and y. plt.scatter(x, y) #reverse x-axis. Notice that the x-axis now ranges from 14 to 0 instead of 0 to 14. Lastly, we could use the following code to reverse both axes:
