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.The first row of pixels is normally at the top of an image. By default, the IMAGE and IMAGESC functions invert the y-axis direction when the image is displayed on an axes by setting the 'YDir' property to 'reverse.' To invert the y-axis direction, set the 'YDir' property to 'normal', as follows:Flip the Y-axis ticks without flipping the plot. Learn more about scatter, 2d plots, ticks . ... If you are plotting a matrix via imagesc or something similar, below method helps in inverting the tickAxes without flipping the data. ... Find the treasures in MATLAB Central and discover how the community can help you! Start Hunting!Flipping images is easy and straightforward in MATLAB. If you want to flip your array up to down, use flipud : udA = flipud (A); imagesc (udA) Or you can simply type. imagesc (flipud (A)) to make the image of A upside down. Similarly, to flip your array or image left to right, use. lrA = fliplr (A); imagesc (lrA)So the x-axis and y-axis should look like the example solution in this post ( matlab multiple x axis one below another ). In case of a imagesc plot a double x-axis is not that difficult with the code of johan of the example solution and some random data. Z = rand(20,30); Y = 32.*(1:size(Z,1));F: the frequencies you want the spectrum evaluated at. fs: the sampling frequency of your signal. Then plot the spectrogram with: subplot(313); imagesc( T, F, log(S) ); %plot the log spectrum. set(gca,'YDir', 'normal'); % flip the Y Axis so lower frequencies are at the bottom. Note: The quality and interpretability of a spectrogram …The code example is not good. The first two lines are not needed because variables xand y are not used. subplot(1,1,1) is also not necessary and axis(..) has no effect because it comes before imagesc. If it came after it would actually change the part of the data that is shown, so better not using it at all here. –There is no picture, only a line like the one provided. This plot (x,-y) doesn't work plot (x,-y) because it converts the y axis in negative values. This second option either. I don't want to do any changes to the axis, only flip the data.

So if I have a 500x400 image, the y and x scale will go frim 1 to 500 and 1 to 400. Instead, I would like that those axis show me the position in mm. My 500x400 image represent a real image of 10mm x 8mm. I would like my axis to show me values ranging from 0 to 10mm and 0 to 8mm.x and y do not affect the elements in C; they only affect the annotation of the Axes. If length(x) > 2 or length(y) > 2, imagesc. ignores all except the first and last elements of the respective vector. Algorithm. imagesc creates an image with CDataMapping set to scaled, and sets the Axes CLim to the value passed in clims. ExamplesBest Answer.
