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:But it does not matter:) ). The problem is that when I plot the matrix using pcolor () the matrix is ploted mirrored. An example: A= [1 0 0;0 1 0;0 0 1]; If I plot the matrix, the cell (0,0) will be plotted not in the top left corner but in the bottom left corner. (Its obvious the start of the axes is (0,0) I understand that the function is ...Jul 17, 2018 · I need to flip just the y axis and not the image itself. I'm using the image function to plot this image, however due to the way matlab reads images, it results in the Y axis being from top to bottom. I tried using (set(gca,'YDir','normal')) but this flips the image too. Is there a way to just flip the Yaxis? Any help would be appreciated.

However, I would like to know how can I scale this xaxis 400 to intervals like between 0:20 = 1, 20:40 = 2 until 380:400 = 20; and setting x axis of imagesc in 0-20 scale with the values of 0-20.

I want to make data analysis from the image. The data points are logarithmic linearly located along both x and y axis, i.e. 0.01, 0.1, 1, 10, ....So when the image is plotted with imagesc, data should be evenly distributed in the logarithmic arranged matrix. I am also interested in some special points, so xlabel and ylabel are set explicitly.

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))]);

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:I want to make data analysis from the image.
