Matlab绘制带误差线的柱状图
Matlab可绘制带误差线的柱状图(需下载barweb (BARgraph With Error Bars) - File Exchange - MATLAB Central并设置路径),成图如下所示。
代码:
close all;clear;clc;
X = [0.2267 0.1423 0.1427 0.1038; 0.1567 0.1184 0.1479 0; 0.1199 0.1035 0.1643 0; 0.1900 0.1540 0.1631 0]; %(系列数据)
E = [0.2808 0.1069 0.1092 0.1006; 0.1614 0.1003 0.1001 0; 0.1277 0.0789 0.1181 0; 0.2398 0.1518 0.1433 0];%(标准差)
legends = {'2019','2020','2021','2022'};%(图例)
groupnames = cell(4,1);
groupnames{1} = '1';groupnames{2} = '2';groupnames{3} = '3';groupnames{4} = '4';%(分组名称)
Title = '';
Xlabel = 'X';
Ylabel = 'Y';
barweb(X,E,1,groupnames,Title,Xlabel,Ylabel,jet,'none',legends,2,'plot');

如果使用高版本Matlab,运行过程过程中可能会遇到以下(以及其他)问题

最后贴一下我自己修改后的代码(Maltab R2016a版本):
function handles = barweb(barvalues, errors, width, groupnames, bw_title, bw_xlabel, bw_ylabel, bw_colormap, gridstatus, bw_legend, error_sides, legend_type)
%
% Usage: handles = barweb(barvalues, errors, width, groupnames, bw_title, bw_xlabel, bw_ylabel, bw_colormap, gridstatus, bw_legend, error_sides, legend_type)
%
% Ex: handles = barweb(my_barvalues, my_errors, [], [], [], [], [], bone, [], bw_legend, 1, 'axis')
%
% barweb is the m-by-n matrix of barvalues to be plotted.
% barweb calls the MATLAB bar function and plots m groups of n bars using the width and bw_colormap parameters.
% If you want all the bars to be the same color, then set bw_colormap equal to the RBG matrix value ie. (bw_colormap = [1 0 0] for all red bars)
% barweb then calls the MATLAB errorbar function to draw barvalues with error bars of length error.
% groupnames is an m-length cellstr vector of groupnames (i.e. groupnames = {'group 1'; 'group 2'}). For no groupnames, enter [] or {}
% The errors matrix is of the same form of the barvalues matrix, namely m group of n errors.
% Gridstatus is either 'x','xy', 'y', or 'none' for no grid.
% No legend will be shown if the legend paramter is not provided
% 'error_sides = 2' plots +/- std while 'error_sides = 1' plots just + std
% legend_type = 'axis' produces the legend along the x-axis while legend_type = 'plot' produces the standard legend. See figure for more details
%
% The following default values are used if parameters are left out or skipped by using [].
% width = 1 (0 < width < 1; widths greater than 1 will produce overlapping bars)
% groupnames = '1', '2', ... number_of_groups
% bw_title, bw_xlabel, bw_ylabel = []
% bw_color_map = jet
% gridstatus = 'none'
% bw_legend = []
% error_sides = 2;
% legend_type = 'plot';
%
% A list of handles are returned so that the user can change the properties of the plot
% handles.ax: handle to current axis
% handles.bars: handle to bar plot
% handles.errors: a vector of handles to the error plots, with each handle corresponding to a column in the error matrix
% handles.legend: handle to legend
