绘图gca的用法

1、(转)Matlab坐标修改gca1、坐标轴删除set(gca,xtick，）%去掉x轴的刻度set(gca,ytick，) %去掉xy轴的刻度set(gca,xtick,ytick,) %同时去掉x轴和y轴的刻度2、Matlab中“坐标轴刻度”的不同风格x=1:8;subplot(2,2,1)plot(x)%tick style 0(auto)subplot(2,2,2)plot(x)set(gca,xtick,1 3 6 8);%style 1set(gca,ytick,);%style 2subplot(2,2,3)plot(x)set(gca,xtick,1 3 6 8);set(gca

2、,xticklabel,sprintf(.4f|,get(gca,xtick);%style 3set(gca,ytick,2 4 5 7);set(gca,yticklabel,Two,Four,Five,Seven);%style 4subplot(2,2,4)plot(x)set(gca,xminortick,on);%style 5set(gca,ticklength,0.05 0.025);%style 6set(gca,tickdir,out);%style 7另附Maltab坐标调整程序一段：x=20:10:20000;y=rand(size(x);semilogx(x,y);s

3、et(gca,XLim,20 20000);set(gca,XMinorTick,off);set(gca,XTick,20 31.5 63 125 250 500 1000 2000 4000 8000 16000);set(gca,XGrid,on);set(gca,XMinorGrid,off);3、matlab坐标刻度调整subplot(3,2,1)plot(x)title(默认格式)subplot(3,2,2)plot(x)set(gca,xtick,1 3 6 8);set(gca,ytick,);title(X自定义间隔，Y关闭)subplot(3,2,3)plot(x)set(

4、gca,xtick,1 3 6 8);set(gca,xticklabel,sprintf(.4f|,get(gca,xtick)set(gca,ytick,2 4 5 7);set(gca,yticklabel,Two,Four,Five,Seven);title(XY自定义间隔、精度及显示方式)subplot(3,2,4)plot(x)set(gca,xminortick,on);%style 5set(gca,ticklength,0.05 0.025);set(gca,tickdir,out);title(XY坐标刻度显示方式)subplot(3,2,5)plot(x)set(gca,

5、xtick,min(x) (max(x)+min(x)/2 max(x);set(gca,ytick,min(x) (max(x)+min(x)/2 max(x);title(论文中常用的标准3点式显示)x=20:10:20000;y=rand(size(x);subplot(3,2,6)semilogx(x,y);set(gca,XLim,20 20000);set(gca,XMinorTick,off);set(gca,XTick,20 31.5 63 125 250 500 1000 2000 4000 8000 16000);set(gca,XGrid,on);set(gca,XMinorGrid,off);title(自定义网格显示)%顺便附上可以格式化坐标刻度的程序段x=get(gca,xlim);y=get(gca,ylim);set(gca,xtick,x(1) (x(1)+x(2)/2 x(2);set(gca,ytick
