If flipping only the y axis is what makes it correct then I would suggest you plot your data correctly in the first place so that it is consistent. Flipping the y axis is just a matter of whether you have the origin at the top or the bottom, but the data will move with it, if you just change the YDir setting of the axescomp.soft-sys.matlab.

So you can simply use imresize () to calculate the new size. The new number of columns will be. Theme.3. You can use the function flip to flip any array along one axis: Aa = flip(A,2); This will work for both a gray-scale and an RGB image. This is equivalent to the following indexing expression for a 3D array (such as an RGB image): Aa = A(:,end:-1:1,:); Tip: If you are going to write a loop, always make the inner loop the one that loops over ...

But I want to force both the axis between 0 and 1. Any suggestions ?Open in MATLAB Online. In the case where the x axis is to be a duration array (rather than a datetime array): First, plot something using an x axis in the same time units as you want the imagesc to be labeled with. Then. Theme. Copy. hold on. h = imagesc (I); set (h, 'XData', [1, seconds (t (end))]);Starting in MATLAB R2023a when you change the Rotation property of an axis label in a 2-D plot, the HorizontalAlignment and the VerticalAlignment properties of the label automatically update to prevent overlap between the label and the axes.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 …

image(C) displays the data in array C as an image. Each element of C specifies the color for 1 pixel of the image. The resulting image is an m -by- n grid of pixels where m is the number of rows and n is the number of columns in C. The row and column indices of the elements determine the centers of the corresponding pixels.

The problem is, I presume, that although your image shows 15 numbers along in each axes, the total size of your image in pixels is 450 x 450 - and this is what imagesc is using. So, what you really have is an image with 15 x 15 blocks of 30 x 30 pixels. You can set the axes ticks and labels manually using XTick and XTickLabel:

In order to flip the labeling of the y-axis while keeping the matrix plot unchanged, you can use the " set(gca, 'YDir', 'normal')" or " set(gca, 'YDir', 'reverse')" command after plotting your data with " imagesc" function. This command changes the direction of the y-axis without altering the data in the matrix.
