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:By default matlab takes the x and y axis as the size of the matrix. But I want to force both the axis between 0 and 1.

I have visualized the matrix by transposing it and using the imagesc function to see the distribution of colors. All vectors have been resampled, processed and normalized between 0 & 1 individually.

If flipping only the y axis is what makes it correct then I would suggest you plot your data correctly in the first place so that it is consistent. Flipping the y axis is just a matter of whether you have the origin at the top or the bottom, but the data will move with it, if you just change the YDir setting of the axes

Dear all, I want to change the x-axis direction from right to left but also keeping the values to be not affected (reversed/flipped). when I used the fooling command the mentioned problem is caused: Theme. Copy. set (gca, 'XDir','reverse') How can I solve that? Potentially easy matlab question here, but I've searched and can't sort out how to do this. I've got a variables, which plot like this: I simple want the x axis to be the y axis and vice versa.

Going by the Matlab documentation for imagesc, it says: imagesc(x,y,C) displays C as an image and specifies the bounds of the x- and y-axis with vectors x and y. If x(1) > x(2) or y(1) > y(2), the image is flipped left-right or up-down, respectively. If x and y are scalars, the image is translated to the specified location (x,y) such that the ...Algorithm. imagesc creates an image with CDataMapping set to scaled, and sets the Axes CLim to the value passed in clims. Examples. If the size of the current colormap is 81-by-3, The left Image maps to the gray colormap using the statements. load clown. imagesc(X) colormap(gray)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. What am I doing wrong with my code? I've tried using ydata straight, flipping it, etc but that hasn't worked. Whenever I set YDir it always flips the image so that the red in at the bottom, but then the axis looks ok.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.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.'

Feb 19, 2019 · 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:

When you use imagesc, your x and y data are automatically selected to be the matrix column or row where your data point was found. If you change your y-limits to be outside of this range then your data will disappear. However, if you just want your y axis to be labelled from 22 to 26, then this should work: Array = rand(5,4000);21. Link. Open in MATLAB Online. After your plot call, add this line: Theme.

Rather than mirroring the image vertically, it mirrors the axis marks. While not an answer the question it can be an alternative in some cases. In addition it remaps the axis to a new range instead of the …17. To reverse an axis, you can set the 'XDir' or 'YDir' property of the current axes to 'reverse': set(gca,'XDir','reverse'); %# This flips the x axis. Keep in mind that flipping an axis in this way flips everything in the plot as well. This probably isn't what you want to do for the y axis.
