In this code, we plot the video and eye position separately to adjust the y-axis limits of both plots to match the reversed y-axis of the eye position data. Then we plot them together using imshow for the video and plot for the eye position, with the hold on and hold off commands to combine the plots. We also adjust the y-coordinates of the eye ... Location of y-axis tick marks and labels. This property controls where MATLAB displays the y-axis tick marks and labels. Setting this property to right moves the y-axis to the right side of the plot from its default position on the left side. See the plotyy function for a simple way to use two y-axes.

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. I tried using (set(gca,'YDir','normal')) but this flips the image too. Is there a way to just flip the Yaxis? Any help would be appreciated.21. Link. After your plot call, add this line: Theme. Copy. set (gca, 'YDir','reverse') See the documentation for Axes Properties for details.Description. example. imagesc(C) displays the data in array C as an image that uses the full range of colors in the colormap. Each element of C specifies the color for one 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.In order to flip the labeling of the y-axis while keeping the matrix plot unchanged, you can use the " set(gca, 'YDir', 'normal')" or " set(gca, 'YDir', 'reverse')" command after plotting your data with " imagesc" function. This command changes the direction of the y-axis without altering the data in the matrix.More specifically, I have 15 daily prices so what I did was building a vector from 0 to 15 and use flipr to reverse the order of my raw vector but it doesn't work because also the price of the option was reversed.

Description. B = flip(A) returns array B the same size as A , but with the order of the elements reversed. The dimension that is reordered in B depends on the shape of A: If A is vector, then flip(A) reverses the order of the elements along the length of the vector. If A is a matrix, then flip(A) reverses the elements in each column.
In this code, we plot the video and eye position separately to adjust the y-axis limits of both plots to match the reversed y-axis of the eye position data.
