%% 记录自己绘图遇到的一些问题

1.输出指定尺寸大小图片

set(gcf,'unit','centimeters','position',[10 5 7 4.3])

【8.5  5】为指定输出图片宽和高 cm

【10  5】为指定输出图片位置

根据word中插图单双栏，可设置成【7  4.3】（双栏），【14  8.6】（单栏）

2.绘制条形图

amax = [ 0.1;0.198;1.191] ;
arms = [0.023;0.085;0.315 ] ;

X = categorical({'RMS(Y)','MAX(Y)'});
X = reordercats(X,{'RMS(Y)','MAX(Y)'});
% x = [1 2];
vals = [arms,amax];
b = bar(X,vals,1);

xtips1 = b(1).XEndPoints;
ytips1 = b(1).YEndPoints;
labels1 = string(b(1).YData);
text(xtips1(1)-0.05,ytips1(1),labels1(1),'HorizontalAlignment','center','VerticalAlignment','bottom')
text(xtips1(2),ytips1(2),labels1(2),'HorizontalAlignment','center','VerticalAlignment','bottom')
xtips2 = b(2).XEndPoints;
ytips2 = b(2).YEndPoints;
labels2 = string(b(2).YData);
text(xtips2-0.06,ytips2+0.05,labels2,'HorizontalAlignment','center','VerticalAlignment','bottom')
xtips2 = b(3).XEndPoints;
ytips2 = b(3).YEndPoints;
labels2 = string(b(3).YData);
text(xtips2,ytips2,labels2,'HorizontalAlignment','center','VerticalAlignment','bottom')

3.一些字体设置大小

输出尺寸【14  8.6】

legend('30km/h','50km/h','80km/h','fontsize',12)
xlabel('时间t/s','fontsize',15,'FontWeight','bold');
ylabel('前轮转角/（deg）','fontsize',15,'FontWeight','bold');
set(gcf,'unit','centimeters','position',[10 5 14 8.6])
box off
ylim([-12 10])
xlim([0 20])

输出尺寸【7  4.12】

legend 字体 8

xy label 字体10

线宽 2.5
