MATLAB Graphics 2-D and 3-D Plots Line Plots Two y-axis. Find more on Two y-axis in Help Center and File ...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'.

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'.

Potentially easy matlab question here, but I've searched and can't sort out how to do this. I've got a variables, which plot like this: I simple want the x axis to be the y axis and vice versa.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 ...

Specify the minimum y-axis limit as 0 and let MATLAB choose the maximum limit. [X,Y,Z] = peaks; surf(X,Y,Z) ylim([0 inf]) Set Limits for y-Axis with Dates. Open Live Script. Create a horizontal bar chart with dates along the y-axis. Set the y-axis limits to range from June 1, 2014 to June 10, 2014. The y-direction is 'reverse' in image plots, so to correct it: set (gca, 'YDir','normal') . If using matplotlib you can try: matplotlib.pyplot.xlim(l, r) matplotlib.pyplot.ylim(b, t) These two lines set the limits of the x and y axes respectively. For the x axis, the first argument l sets the left most value, and the second argument r sets the right most value. To revert X-axis, we use matplotlib.axes.Axes.invert_xaxis and to invert Y-axis we use matplotlib.axes.Axes.invert_yaxis. We can revert either any one of the axes or both axes using above methods. import numpy as np. import matplotlib.pyplot as plt. x = np.linspace(-3, 3, 100)Label the x -axis and return the text object used as the label. plot((1:10).^2) t = xlabel( 'Population' ); Use t to set text properties of the label after it has been created. For example, set the color of the label to red. Use dot notation to set properties. t.Color = 'red';

By default, the x-axis and y-axis appear along the outer bounds of the axes.Change the location of the axis lines so that they cross at the origin point (0,0) by setting the XAxisLocation and YAxisLocation properties of the Axes object. Set XAxisLocation to either 'top', 'bottom', or 'origin'.Set YAxisLocation to either 'left', 'right', or 'origin'.Add another sine wave to the axes using hold on. Keep the current axis limits by setting the limits mode to manual. y2 = 2*sin(x); hold on. axis manual. plot(x,y2) hold off. If you want the axes to choose the appropriate limits, set the limits mode back to automatic.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.Matlab用imagesc函数画图时，一般将图像矩阵的起点 (1,1) 画在左上角，如果该点代表的实际位置是物体的左下角，那么Matlab所画的看起来就是倒立的图像，因此需要翻转Y轴。. 以下介绍几种方法可以实现这一功能：.
