matlab xlabel位置的设置方式

xlabel(‘time",‘FontSize",12);

xlabel(‘time",‘position",[900,1870],‘FontSize",12);

pos=axis;%取得当前坐标轴的范围，即[xmin xmax ymin ymax]
xlabel(‘time",‘FontSize",12, ‘Position",[pos(2) pos(3)])

x=0:pi/50:2*pi;
y=sin(x);
plot(x,y);
pos=axis;%取得当前坐标轴的范围，即[xmin xmax ymin ymax]
xlabel("x轴","position",[pos(2) 1.15*pos(3)]);%设置x轴标签的文本在图的右下方，1.15这个值根据自己的需要可以调整
