Matlab reverse y axis.

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 ...

Matlab reverse y axis. Things To Know About Matlab reverse y axis.

To change direction of y axis, including axis labels and plotted values, you use. set(gca,'YDir','reverse') When you plot an image, for example using imagesc, the YDir property is automatically set to reverse. So, to change it, set it to normal: set(gca,'YDir','normal') edited Dec 25, 2013 at 20:25. answered Dec 25, 2013 at 19:33.Learn more about parallel plot, y axis, reverse direction Hi all, I have plotted a parallel plot in Matlab.

Using the FirstCrossOverValue and SecondCrossoverValue properties of the Axes ' NumericRuler objects ( XAxis, YAxis, ZAxis ), we can position the secondary axis in the desired location. The basic idea is illustrated in the example below. This is for the z-axis, but the same approach can be used for y or x. clear; close all; clc.x = linspace (0,10); y = sin (x); plot (x,y) 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.

I have multiple things plotting on one graph and have one of the axes on the right side and the other two on the left. 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!

In particular, the app designer window is not a figure window, and so a new one is created.

It does in my version of matlab (7.6.0.324 (R2008a)) (you can retrieve version number with the version command). If you want to place the x-axis somewhere in the middle of the picture, this is not possible in my version: the x-axis is either at the top or at the bottom (you can set this with the "XAxisLocation" property). -Reverse the X and Y axis values in a 3D plot.

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!Simply reverse the order of the "axis" command and the "plot" command. When you use "axis" before "plot", "plot" overrides the "axis" command with default axes. Switching these two lines will fix the problem. However, if you want to animation individual points, there is also a "set" command which works wonders for neat animations. Check …p ( x) = p 1 x n + p 2 x n − 1 + ... + p n x + p n + 1. The polynomial coefficients in p can be calculated for different purposes by functions like polyint, polyder, and polyfit, but you can specify any vector for the coefficients.

I know it has something to do with gca but cannot figure out the right code. Please help me. In the default 2-D view, the x-axis values increase from left to right and the y-axis values increase from bottom to top. The z-axis points out of the screen. You can change the direction of increasing values by setting the associated property to reverse. For example, setting XDir to reverse, set(gca,'XDir','reverse')

Link. Hello Giorgia, 'fplot' is mostly used to plot a curve defined by y=f (x) where 'x' is input and 'y' is output which is the standard convention. I would recommend you use a simple 'plot' function since you will get control over how you want to represent the data in the plot. Refer to the following documentation for more details:

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.

If set to another axis id (e.g. `x2`, `y`), the range of this axis will match the range of the corresponding axis in data-coordinates space. Moreover, matching axes share auto-range values, category lists and histogram auto-bins. Note that setting axes simultaneously in both a `scaleanchor` and a `matches` constraint is currently forbidden.Include a variable value in the title text by using the num2str function to convert the value to text.
