This is the linear image: This is the Y axis log scale image: They are same except the fake log scale Y axis. My original code is : Theme. Copy. imagesc (x,y,log10 (image_spectrogram (1:floor (Fs/2),:)+1)); 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) However the Y axis nees to go from ~6 in the bottom left to ~19 in the top left - the axis in this image are reversed.
