Matlab imagesc flip y axis.

To update this answer, since it is still a popular Google result: As of R2014a, the correct way to flip the Y axis is the following: >> axis ij. This change can be reversed through the following command. >> axis ji. To flip the X or Z axes, do the following. set(gca,'XDir','reverse'); set(gca,'ZDir','reverse');image(C) displays the data in array C as an image. Each element of C specifies the color for 1 pixel of the image. The resulting image is an m -by- n grid of pixels where m is the number of rows and n is the number of columns in C. The row and column indices of the elements determine the centers of the corresponding pixels.hold on. % Now you can convert from datetime to numerics using ruler2num. x = ruler2num (times, gca ().XAxis); % Now pass the double data to imagesc. im=imagesc (x,yvals,colors); % Finally, because hold was on, you need to manually set the limits (which. % is normally done for you by imagesc) and turn on the box.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.Hi, How to reverse the Y axis while displaying images with imagesc function..

Here i have considered your x-axis variable is 'x' and initial y-axis variable is 'y' Final y-axis variable is considered to be 'newy' Monique Embury on 16 Oct 2019From your question I infer that you want to set the x-axis labels from -180 to 180, and the y-axis labels from -90 to 90. To do this, you should change the XTickLabel and YTickLabel properties of the axis object (note that you'll also need to adjust the number of ticks in each axis by modifying the XTick and YTick properties accordingly).

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.'

Whenever I set YDir it always flips the image so that the red in at the bottom, but then the axis looks ok.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.To update this answer, since it is still a popular Google result: As of R2014a, the correct way to flip the Y axis is the following: >> axis ij.

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'.
