1、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. 1
set(gca,'ytick',[]);%style. 2
subplot(2,2,3)
plot(x)
set(gca,'xtick',[1 3 6 8]);
set(gca,'xticklabel',sprintf('%.4f|',get(gca,'xtick')));%style. 3
set(gca,'ytick',[2 4 5 7]);
set(gca,'yticklabel',{'Two','Four','Five','Seven'});%style. 4 subplot(2,2,4)
plot(x)
set(gca,'xminortick','on');%style. 5
set(gca,'ticklength',[0.05 0.025]);%style. 6
set(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);
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'); 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(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. 5 set(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,'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',[y(1) (y(1)+y(2))/2 y(2)]); ------------- get(gca,'xlim');是获取最大最小刻度的 如果需要获取所有在坐标轴上显示的刻度,需要使用get(gca,'ytick')
