如何在 Matlab 中从 Excel 文件中绘制条形图？ [关闭]

Question

我是 Matlab 的新手。假设我在 excel 中有一个表，passenger.xls，如下所示：

Id  StaName   In  Out 

1   StationA  10  80

2   StationB  50  40

3   StationC  25  45

如何在 Matlab 中制作适当的条形图，如上表所示，以 StationName 显示 In 和 Out？

请给我一个分步说明来完成这项任务吗？非常感谢您的帮助。

Answer 1

% A very simple example that does not attempt any checks on the input data.

% Load your Excel file into MatLab.
% Replace YourExcelFile with the correct file name
[numeric,textual,raw]=xlsread('YourExcelFile');

% Assuming that the example data starts in cell A1 and is of the format
% shown, plot the 'In' and 'Out' numeric data in a bar graph.
bar(numeric(1:end,3:end));

% Replace the numeric labels on the x axis with the values from StaName.
% Do this by setting the XTickLabel property on the current graph axis.
set(gca,'XTickLabel',textual(2:end,2));
