Matlab imagesc flip y axis.

For example, if I have a 512x512 image and I want my x-axis to be a function of time. Maybe time increases by 1 sec for the first 256 columns and then jumps by 60 secs and then returns back to 1 sec intervals.

If length(x) > 2 or length(y) > 2, imagesc ignores all except the first and last elements of the respective vector. imagesc creates an image with CDataMapping set to scaled, and sets the axes CLim property to the value passed in clims. Examples. If the size of the current colormap is 81-by-3, the statements. clims = [ 10 60 ] imagesc(C,clims)

As you can see the images in first row are now scaled equally on X and Y axis (Y axis is longer than the X-axis) even though the size of the image matrix is 100x100 for each image on first row. Can someone help with how to make images in first row look like squares than rectangles which I get currently. Thanks.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:plot(x,y) Add another sine wave to the axes using hold on. Keep the current axis limits by setting the limits mode to manual. y2 = 2*sin(x); hold on. axis manual. plot(x,y2) hold off. If you want the axes to choose the appropriate limits, set the limits mode back to automatic.subplot (1,2,2) plot (x,y) axis equal; axis tight. These can be combined by specifying the axis ranges for imagesc (). In order to get the orientation of the plot and image to match, the axis flipping that imagesc () uses needs to be undone. Theme.
