I would like to reverse the order of the right side label only. I do not want to reverse the axis. Is there a way to do this? Thanks!
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:
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. Exp = [0:15]; %days to expiration. P = rand (1,15); %fake daily prices. plot (Exp,P) %is all reversed not just the days to expiration.Accepted Answer. 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'. Alternatively, if you want the values to decrease from bottom to top, then set the value to 'reverse'.

To plot a set of coordinates connected by line segments, specify X and Y as vectors of the same length. To plot multiple sets of coordinates on the same set of axes, specify at least one of X or Y as a matrix.To reverse the y-axis, you can set the YDir property of the axes object to 'reverse'. Here's some sample code to get you started: % Load the video file. v = VideoReader ('my_video.mp4'); % Create a figure and axes to display the frames. fig = figure; ax = axes ('Parent', fig); % Set the y-axis direction to 'reverse'.
A pseudocolor plot displays matrix data as an array of colored cells (known as faces ). MATLAB ® creates this plot as a flat surface in the x - y plane. The surface is defined by a grid of x - and y -coordinates that correspond to the corners (or vertices) of the faces. The grid covers the region X=1:n and Y=1:m, where [m,n] = size(C).
In the following code: a = [180 170 150 90 45 5 0 -5 -30 -70 -100 -125 -150 -175]; b = [1 2 3 4 5 6 7 8 9 10 11 12 13 14]; plot (a, b,'.') How i can plot the b variable (as the y-axis) with the high numbers down and the low numbers up in the plot? Thanks. 0 comentarios. Iniciar sesión para comentar.

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 axesHow to reverse Y axis on image?.

I want to reverse the y axis so that the initial value is at the top and also the x axis start from that point only. 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.yscale(scale) sets the scale of the y-axis to be linear or logarithmic in the current axes. Specify scale as "linear" or "log" .
