matlab绘图

双y坐标，条形图+折线图，y轴刻度值离散化

plot（）与semilogy（）对比

效果：

 

 程序：

clear all;clc
[num,txt,raw]=xlsread('matlab绘图数据.xlsx'); %读入数据
year=num(:,1);
x=num(:,2);
ux=num(:,3);
ux1=num(:,4);
ux2=num(:,5);
ux3=num(:,6);
figure(1);
yyaxis left;
bar(year,x, 0.5) %绘制条形图，0.5为条形图宽度
set(gca,'ycolor','k'); %左边Y轴颜色
axis([2010,2020,0,350]); %限制x,y轴坐标值范围
% hold on; 
yyaxis right;
% plot(year,ux,'k-s',year,ux1,'g-d',year,ux2,'b-o',year,ux3,'r-+');%绘制折线图（不扩展y轴）
semilogy(year,ux,'k-s',year,ux1,'g-d',year,ux2,'b-o',year,ux3,'r-+');%绘制折线图
set(gca,'YLim',[-1 0.7]);
mu=[0.0008348 0.002 0.005 0.01 0.02 0.05  0.1 0.2 0.4 0.7]; % 设置刻度值
set(gca,'ytick',mu,'yticklabel',{'0' '0.002' '0.005' '0.01' '0.02' '0.05' '0.1' '0.2' '0.4' '0.7'}); %纵坐标设置
% set(gca,'ytick',{'0' '0.002' '0.005' '0.01' '0.02' '0.05' '0.1' '0.2' '0.4' '0.7'});
set(gca,'ycolor','k'); %右边Y轴颜色
set(gca, 'YMinorTick', 'off') %去除没有刻度值的刻度线
axis([2010,2020,0,0.7]);
legend('x','ux','ux1','ux2','ux3','orientation','horizontal'); %曲线注释
box off %删除上边框
