For example: load clown imagesc(X) colormap(map) Instead of the y-axis increasing from top to bottom, I would like to have it decreasing from top to bottom.

We can flip the given image vertically (along the x-axis), if we reverse the order of the pixels (elements of the matrix) in each column as illustrated in the below image. Code #1: Using MATLAB Library function. Code #2: Using matrix manipulation. Code #3: Using matrix manipulation (Using loops) Display the water image (vertically flipped image).

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.

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.There is more than flip flops for men for summer shoe style.

After displaying an image with the IMAGESC function, you can change the axis so it is decreasing from top to bottom. For example, load clownX = flipud(X);imagesc(X)colormap( map )axis( 'xy')

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:First, load in the image, the generate (x,y) pairs for each intensity in the image. This is done with meshgrid. Once you do this, use scatter to plot each point assuming z = 0 and make the colour of each point the actual intensity seen at the image coordinate. However, you will only see this in a 2D perspective as scatter is naturally 2D.

If just the former, then you could do. hImg = imagesc (...); The above code just flips the y-axis tick labels so that their order is reversed. NOTE that this does not change the manner in which you can access the data in the image, all it does is flip the labels.However, when I try plotting my coordinates over an image, it changes the order of my y-axis from ascending to descending and my plots appear flipped on the x-axis. My code for plotting wanted_city and locations is the same when using borders function.Nov 23, 2021 · Copy. imagesc (n) ax = gca; ax.XTick = x; ax.YTick = y; ax.YDir = 'normal'; What I get is this: Clearly, it does not even put all the ticks and the ticks are not even correct. The data x and y varies between said magnitude and each succesive element in their vectors jump by an order of magnitude less than the previous value, for example: 1e-1 ...
