matlab绘制多曲线对比图

**contourf(x,y,z);%等高线图

colormap(gray);设定图形颜色

scatter(x,y,’o’);%绘制散点图

X=A(:,1); Y=A(:,2); Z=A(:,12);

[x,y,z]=griddata(X,Y,Z,linspace(min(X),max(X),200)’,linspace(min(Y),max(Y),200),’v4’);%利

用离散的地理坐标得到Zn的二元拟合连续函数,进行插值

mesh(x,y,z);shading flat%网格状的三维曲面图

surfl(x,y,z);shading flat%光滑的三维曲面图

colormap(”)%设定曲面颜色

gray,winter,flag,cool..

%给图形家标注

title(”) %图形标题

%二维的

gtext(‘标注内容’,’fontsize’,15);%任意位置的标注

xlabel(‘..’,”,..,”,..);

ylabel(‘..’,”,..,”,..);

%三维图形的标注
