Matlab reverse y axis

Show activity on this post. The reason why ylim doesn't work if you put it before the plot command is that there is no axes object it can relate to. So there are two options: First, you create an axes object and hold it with hold on, so the upcoming plot is plotted on the same axis. ax = axes; hold on; ylim([0, 1.2])

I want to change the x-axis direction from right to left but also keeping the values to be not affected (reversed/flipped). when I used the fooling command the mentioned problem is caused: set(gca, 'XDir' , 'reverse' )ax contains two handles, one to each axis produced by plotyy. We can use these to set the format of the x-axis using datetick. The two axes have to be set to the same values otherwise you'll get weird overlapping text, and it seems datetick will only handle one axis at a time, hence a loop: for n = 1:2 datetick(ax(n),'x','dd-mmm'); endOct 28, 2018 · Edited: DGM on 11 Feb 2024.

Log(A) calculates the natural logarithm of each...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'.Starting in R2019b, you can display a tiling of plots using the tiledlayout and nexttile functions. Call the tiledlayout function to create a 2-by-1 tiled chart layout. Call the nexttile function to create the axes objects ax1 and ax2.Plot random data into each axes. Then set the x-axis tick values for the lower plot by passing ax2 as the first input argument to the xticks function.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 ...

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.
