Flipping images is easy and straightforward in MATLAB. If you want to flip your array up to down, use flipud : udA = flipud (A); imagesc (udA) Or you can simply type. imagesc (flipud (A)) to make the image of A upside down. Similarly, to flip your array or image left to right, use. lrA = fliplr (A); imagesc (lrA)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:

Commented: Iain on 24 Jan 2014. My code reads raw data from a file (that ends with .raw) and assigns arrays from the raw data such as data = raw (1:512, 1:128) but when I display this data with the statement as follows: imshow (data, 'Parent', handles.ax), the x-axis and y-axis data were displayed in reverse.For one New York real estate mogul, fixer-uppers can be pricey.

To invert the y-axis direction, set the 'YDir' property to 'normal', as follows:Starting in MATLAB R2023a when you change the Rotation property of an axis label in a 2-D plot, the HorizontalAlignment and the VerticalAlignment properties of the label automatically update to prevent overlap between the label and the axes.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 ...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 axes

Flipping images is easy and straightforward in MATLAB. If you want to flip your array up to down, use flipud : udA = flipud (A); imagesc (udA) Or you can simply type. imagesc (flipud (A)) to make the image of A upside down. Similarly, to flip your array or image left to right, use. lrA = fliplr (A); imagesc (lrA)imagesc (x,y,C) displays C as an image and specifies the bounds of the x- and y-axis with vectors x and y. Therefore, the command: figure, imagesc(t, 1 : n, values'); colorbar; illustrates the image on uniform time grid. Edit: It's possible to re-sample the timeseries with higher uniform resolution. But my timeseries is already very large.The code example is not good. The first two lines are not needed because variables xand y are not used. subplot(1,1,1) is also not necessary and axis(..) has no effect because it comes before imagesc. If it came after it would actually change the part of the data that is shown, so better not using it at all here. –I can see that both the y axis label ‘Relative Roughness e/D’ and the yticks appear at the right of your plot, so I’m assuming you would like to see the yticklabels on the right as well. For that you can use the yticks and yticklabels commands as shown below, and adjust the values to match your need.How to change image axis labels. Asked 11 years, 2 months ago.

The imagesc is wrong, because the y-axis is wrong, and the lines are not where they are supposed to be. As you can see, the lines of the imagesc image do not agree with the lines of the pcolor image. I cannot seem to get the imagesc y-axis to agree with the pcolor y-axis, and thus give me a similar plot.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.

Similarly, to flip your array or image left to right, use. lrA = fliplr (A); imagesc (lrA) or just. imagesc (fliplr (A))The default behavior of imshow is to put the origin of the coordinate system in the upper left corner. This is different from plotting scientific data, such as two entities x and y against each other, where the origin, i.e. the point corresponding to the coordinate (0,0), is in the lower left corner, with the (positive) x-axis extending to the right and the (positive) …I have a matrix(20x400) and I am plotting it with imagesc where y axis having 20 values and xaxis having 400 values. 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.Jul 29, 2010 · 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) colormap (map) axis ('xy')

From the image, I understand that the ticks only go to half the image before starting over and overwriting the previous ticks. Any tips would be highly appreciated. Below is my code for setting the x-axis to the desired tick values; Theme. Copy. colormap gray; %subplot (2,2,1); imagesc (inclinedCyl_d20); ax = gca;

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. Copy. inpict = zeros (250); inpict (50:100,150:200) = 0.6;
