For example, if I have a 512x512 image and I want my x-axis to be a function of time. Maybe time increases by 1 sec for the first 256 columns and then jumps by 60 secs and then returns back to 1 sec intervals. Currently, it appears the image/imagesc functions take the min and max value of the X/Y inputs and creates a vector evenly spaced ...Jul 29, 2010 · 1. Link.

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.1. Link. 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)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;2 Answers. Sorted by: 3. Set Ydir property of the current axes to normal. By default, imagesc uses reverse for YDir. set(gca,'YDir','normal'); See Documentation for Axes properties. Before: After: Note: This completely flips the inside data as well (it supposed to). As you are dealing with matrices, I hope this is what you want.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:
2. 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);
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:
Open in MATLAB Online. To mirror flip an "Image_Original" you can just use flip or rotate and transpose the image : Theme. Image_Flip = flip (Image_Original,2); Image_Flip = imrotate (Image_Original,90)'; Sign in to comment. Thili Mahanama on 29 Apr 2018.1. From the MATLAB help: By default, imagesc plots the y-axis from lowest to highest value, top to bottom. To reverse this, type set(gca,'YDir','normal'). This will reverse both the y-axis and the image. You can also use axis xy which does something similar (the default is axis ij which puts the lowest index on top). i tried axis xy but it ...example of my output image using imagesc function. I included an example of the image that I got so far. The y-axis was left as default, which simply shows that I have over 180 rows in the matrix of my output signal. I changed the x-axis by using linspace to correspond to the range of input parameters from lowest to highest value. However, the ...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:Oct 27, 2017 · Hi. I have a matrix A of size 200*40. I have to generate image for every 200 time steps for which i am using imagesc(A). 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. Any suggestions ?

Learn more about image imagesc matrix plot Hi, I couldn't figure out how to use "image" or "imagesc" to plot my data, hope you can give me a hint on this issue: My data consist of collected data …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.2. Link. Open in MATLAB Online. You can use permute to rearrange the order of the dimensions and axis to to place the origin in the upper left corner: Theme. Copy. S = permute (S, [3 1 2]); % Your plot commands. axis ij.
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 ...

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))]);image(C) displays the data in array C as an image. Each element of C specifies the color for 1 pixel of the image.

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.
