XTick = [-3*pi -2*pi -pi 0 pi 2*pi 3*pi]. For R2014b and R2015a and R2015b there are still some tricks to get the axes labels right but from R2016a I think it was, it should automatically format the ticks given a datetime object such as the. Then set the string array to be the tick labels of the axes. 0. . Therefore, your xtick vector is: time = cellstr (datestr ( [ones (n,1)* [2012 3 10] x zeros (n,2)],'HH:MM')); Data = rand (1,24); plot (x,Data); set (gca,'XTick',0:23); set (gca,'XTickLabel',time); Here, I can plot the change in a certain variable as a function of time (in hours). xlim ( [0 70]); To fix, and make somewhat more robust and versatile, you might try it like this: Theme. set (gca, 'Layer', 'top') but that only brought the major tick marks to the top and left the minor tick marks hidden. Add a comment. OK, I finally found this way: set (gca,'XTickLabel', num2str (get (gca,'XTick')')); I read the ticks and transform them back to strings. yticklabels ('auto') sets an automatic mode, enabling the axes to determine the y -axis tick labels. The easiest way to do this is simply use the following command instead of plot. The 'XTickLabel' property indicates what to display for labels. . When you set XTick, MATLAB automatically resets XTickLabel, but the opposite is not true. In my case, I. Set axes properties after plotting since some plotting functions reset axes properties.

Then set the XTick property using dot notation, such as ax. FontSize = 8; Some of the manipulation I did (in particular changing the YTick and YTickLabel properties of the axes) I could have done via several of the objects as well. set (gca,'XTick',0:pi/2:2*pi)Copy. Use the gca command to obtain the handle of the current Axes. ax = gca; c = ax. Since you are trying to set the limits equal to the range of x, you will probably find the following command most helpful: axis tight But note that it changes both x- and y-axis limits. xlabel ('Log (base 2) of quantity X'); or you can redo the ticks manually. I only want ticks every 10^1. a = get (gca,'XTickLabel'); set (gca,'XTickLabel',a,'fontsize',12,'FontWeight','bold') in a figure where I have 6 subplots and I do this for each subplot separately. plot(1: 10, rand(1, 10)) ax = gca ; % Simply. xtl=get (gca,'XTickLabel'); % 獲取xtick的值.
