matlab座標刻度調整為不等間距刻度程式碼：

subplot(3,2,1)

plot(x)

title("預設格式")

subplot(3,2,2)

plot(x)

set(gca,"xtick",[1 3 6 8]);

set(gca,"ytick",[]);

title("X自定義間隔，Y關閉")

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自定義間隔、精度及顯示方式")

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座標刻度顯示方式")

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("論文中常用的標準3點式顯示")

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("自定義網格顯示")

%順便附上可以格式化座標刻度的程式段

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");是獲取最大最小刻度的

如果需要獲取所有在座標軸上顯示的刻度，需要使用get(gca,"ytick")
