繪圖之水平座標與垂直座標刻度設定

Example:

n = [-100:100];
x = cos(0.1*pi*n);
Hx = stem(n,x,'r--','filled');
set(Hx,'markersize',2);
axis([-110, 110,-2,2]);
xtick = [-100:18:100];
ytick = [-2:0.5:2];
set(gca,'XTickMode','manual','XTick',xtick);
set(gca,'YTickMode','manual','YTick',ytick);
xlabel('n','FontSize',10);
ylabel('x(n)','FontSize',10);

其中水平座標刻度設定

xtick = [刻度由此開始:刻度間隔:刻度結束]

垂直座標刻度設定亦同

ytick = [刻度由此開始:刻度間隔:刻度結束]

更改繪圖axis字型

Example

n = [0:20]; x = [(n-3) == 0];
hd = stem(n,x,'k');
axis([0,20,min(x),max(x)]);
set(get(hd,'Parent'),'FontName','times new roman')


Results

原始圖(字型為Helvetica)

更改後(字型為times new roman)

觀察繪圖區內的屬性

Example:

n = [0:20]; x = [(n-3) == 0];
hd = stem(n,x,'k');
axis([0,20,min(x),max(x)]);
get(get(hd,'Parent'))

Legend中的字型與大小也能變更

Example:

1:10,[1:10].*cos([11:20]),'-g*',1:10,[11:20].*sin([11:20]),'-.k+',...

1:10,[1:10].*cos([21:30]),'--c>',1:10,[21:30].*sin([21:30]),'--yd')

>> h = legend('\fontname{標楷體}{隨機選取}\fontname{times new roman}{Lena}',...

'\fontname{標楷體}{非隨機選取}\fontname{times new roman}{F16}',...
