Matlab imagesc flip y axis.

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.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 axesNov 23, 2021 · 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 ... As you can see the images in first row are now scaled equally on X and Y axis (Y axis is longer than the X-axis) even though the size of the image matrix is 100x100 for each image on first row. ... Put two y-axes on an imagesc image in MATLAB. 2. Axes tick labelling after using imagesc in Matlab. 1. Matlab: multiple images not properly aligned ...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)

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.The first problem is with figure#1; it is inverted in y. The following code reads the .txt file ,which is attached, to be inverted in (y). I am wondering what could be wrong in my code that the data in the .txt file are inverted vertically. Second problem is with figure#4: Why the vertical axis is flipped in figure#4.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 ...

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.

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)

Aug 5, 2015 · 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 ... 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 ?@Learnaholic it covers two images together in the same figure (in your case it is the same aMatrix image). ax1 is the figure handle that the y axis is set on the right, when you imagesc the image for 2nd time, you first get the axes info before imagesc. The position of the 1st image is obtained via get(ax1,'Position').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: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.'

Otherwise, it is hard to remember that we have xAxisValues before yAxisValues …I'd like to use imagesc to plot a matrix with distance on y axis, z in colorbar, and datetime on x axis. Y and Z are in the matrix (12 x 500) and datetime is in seperate vector t (12 x 1). I have the following code but the datetime that shows up on the x axis is January 1, January 2, ...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.Maintain Current y -Axis Limits. Use manual mode to maintain the current y -axis limits when you add more plots to the axes. First, plot a line. x = linspace(0,10); y = sin(x); plot(x,y) Set the y -axis limits mode to manual so that the limits to not change. Use hold on to add a second plot to the axes. ylim manual.Best Answer.

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. –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.
