如何更改MATLAB图中轴上显示的数字的格式? [英] How to change the format of the numbers displayed on an axis in a MATLAB plot?

问题描述

我实际上有3个问题:

我有一个图，其中有成千上万个数据，并且图的轴显示刻度线为.4 .8 1.0 1.2和右下角的* 10 ^ 4.这有点烦人.

I have a plot with data that is in the thousands and my plot's axis is diplaying the tick marks as .4 .8 1.0 1.2 and a *10^4 in the lower right. This is a little annoying.

除了将我的数据除以1000或hardcodig刻度线外，还有一种方法可以将刻度线从.4 * 10 ^ 4更改为4000吗?

Besides dividing my data by 1000 or hardcodig the tick marks is there a way to change to tick marks from .4*10^4 TO 4000?

看起来这应该是微不足道的，但是在浏览完该图的所有属性之后，我似乎找不到位置.

Seems like this should be trivial but aftter browsing through all of the figure's properties I can't seem to get an where.

而且...一旦我得到4000，而不是.4 * 10 ^ 4，就可以旋转刻度线标签，这样它就不会与其他标签重叠.

And...once I get 4000 to apear instead of .4*10^4 is there a way to rotate the tick mark label so it is not overlapping the other labels.

然后..您如何设置有多少个主要"刻度线?

And..how do you set how many "major" tick marks there are?

非常感谢！

推荐答案

尝试以下操作:

x=[4000, 8000, 10000, 12000]; % define the x values where you want to have a tick
set(gca,'XTick',x);  % Apply the ticks to the current axes
set(gca,'XTickLabel', arrayfun(@(v) sprintf('%d',v), x, 'UniformOutput', false) ); % Define the tick labels based on the user-defined format

参考: Mathworks

关于标签旋转，看来Matlab本身并不支持这种功能，但是有人写了

In regards to the label rotation, it seems that Matlab does not support such feature by its own, but someone wrote a script for the label rotation, and you might want to give it a try.
