如何在Matlab中从Excel文件中绘制条形图？

Question

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

Id  StaName   In  Out 

1   StationA  10  80

2   StationB  50  40

3   StationC  25  45

如何在Matlab中制作一个合适的条形图，按照In显示Out和StationName，如上表所示？

请你给我一步一步的指示来完成这项任务吗？非常感谢你的帮助。

% 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));
