Matlab imagesc flip y axis.

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: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. You probably just want to flip the y axis labels ...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.Often, you might want to specify a particular range of data values that map to the full range of the colormap. For this, you can use the following syntax: imagesc( A, [ minValue maxValue]) Example: A = [10 20 30; 40 50 60; 70 80 90]; imagesc( A, [20 80]); colorbar; 📌.

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:

Copy. imagesc (n) ax = gca; ax.XTick = x; ax.YTick = y; ax.YDir = 'normal'; What I get is this: Clearly, it does not even put all the ticks and the ticks are not even correct. The data x and y varies between said magnitude and each succesive element in their vectors jump by an order of magnitude less than the previous value, for example: 1e-1 ...

To specify the first corner …Reversing axes in contourf plot. Learn more about contour, axes, reverseFirst, 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.Hi, How to reverse the Y axis while displaying images with imagesc function.. I have tried as follows, it does the job, however, reverses the image as well. ax = gca; imagesc(x,y,I'); set(g...imagesc(x,y,C) specifies the image location. Use x and y to specify the locations of the corners corresponding to C(1,1) and C(m,n). To specify both corners, set x and y as two-element vectors. To specify the first corner and let imagesc determine the other, set x and y as scalar values. The image is stretched and oriented as applicable.

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.

After displaying an image with the IMAGESC function, you can change the axis so it is decreasing from top to bottom. For example, Theme. Copy. load clown. X = flipud (X); imagesc (X)

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.

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 axesHowever, when I try plotting my coordinates over an image, it changes the order of my y-axis from ascending to descending and my plots appear flipped on the x-axis.

You can change the direction of increasing values along the y-axis by setting the YDir property of the Axes object. If you want the values to increase from bottom to top (2-D view), then set the value to 'normal'. Alternatively, if you want the values to decrease from bottom to top, then set the value to 'reverse'. 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 axesBy default, Matlab gives you the x and y axis of the pixel number. 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.1. Link.
