Matlab-如何在条形图中使用字符串而不是数字 [英] Matlab - How to use strings instead of numbers in bar figure

问题描述

我想使用bar函数获得Matlab图形，但是当绘制实际图形而不是在每个条形图下方显示数字时，我想显示代表绘制的实际值.

I want to obtain a Matlab figure using the bar function but when the actual figure is plotted instead of displaying the numbers underneath each bar I want to display which represents that actual value plotted.

例如，我具有向量x = [1 2 3]，而不是在每个绘制的条形下方显示1、2和3，而是要显示与这些值y = {'sam'; 'alan'; 'ellie'}

For example I am having the vector x = [1 2 3] and instead of showing 1, 2 and 3 beneath each plotted bar, I want to display a string corresponding to one of these values y = {'sam'; 'alan'; 'ellie'}

能否请您解释一下我怎么能得到这个?

Could you please explain how could I obtain this?

推荐答案

x = [1 2 3];
str = {'sam'; 'alan'; 'ellie'};
bar(x)
set(gca, 'XTickLabel',str, 'XTick',1:numel(str))
