MATLAB绘制饼状图

1 基础案例：修改颜色及字体

成图如下：

MATLAB代码如下：

clc
close all
clear
%% 导入数据
load('X.mat');
Y= X(:,1:4);
pathFigure= '.\Figures\' ;

%% 蓄水预测图
% 颜色设置
mycolor = [94,173,232;
          237,119,69;
          170,166,163;
          255 215 0]./255;
colormap(mycolor);      
      
figureUnits = 'centimeters';
figureWidth = 30; 
figureHeight = 10;      

figure(1);
set(gcf, 'Units', figureUnits, 'Position', [0 0 figureWidth figureHeight]);      

pos1 = [0.01 0.05 0.3 0.8];
subplot('Position',pos1)
h1 = pie3( Y(1,:) );
th = findobj(gca, 'Type', 'text');
set(th, 'FontName', 'Times New Roman', 'FontSize', 12)
text( 'string', "(a)", 'Units','normalized','position',[0.15,0.95],  'FontSize',14,'FontWeight','Bold','FontName','Times New Roman' );   

pos2 = [0.31 0.05 0.3 0.8];
subplot('Position',pos2)
h2 = pie3( Y(2,:) );
th = findobj(gca, 'Type', 'text');
set(th, 'FontName', 'Times New Roman', 'FontSize', 12)
set(gca,'FontSize',12,'Fontname', 'Times New Roman');
text( 'string', "(b)", 'Units','normalized','position',[0.15,0.95],  'FontSize',14,'FontWeight','Bold','FontName','Times New Roman' );   

pos3 = [0.62 0.05 0.3 0.8];
subplot('Position',pos3)
h3 = pie3( Y(3,:) );
th = findobj(gca, 'Type', 'text');
set(th, 'FontName', 'Times New Roman', 'FontSize', 12)
set(gca,'FontSize',12,'Fontname', 'Times New Roman');
text( 'string', "(c)", 'Units','normalized','position',[0.15,0.95],  'FontSize',14,'FontWeight','Bold','FontName','Times New Roman' );   

hl = legend( "生活需水","生态需水","工业需水","农业需水" );
set(hl,'Box','off','location','eastoutside','NumColumns',1,'FontSize',12,'FontName','宋体');    

str= strcat(pathFigure, "Figure1", '.tiff');
print(gcf, '-dtiff', '-r600', str);
