1、plot(x, y); // 画图后用axis函数设置坐标轴的范围。2、axis([xmin xmax ymin ymax]); % 设置坐标轴在指定的区间。3、xmin、xmax 表示设置横坐标的最小最大值。4、ymin、ymax 表示设置纵坐标的最小最大值。
1.plot函数 plot函数用于绘制二维平面上的线性坐标曲线图,要提供一组x坐标和对应的y坐标,可以绘制分别以x和y为横、纵坐标的二维曲线。 例: t=0:0.1:2*pi; x=2*t; y=t.*sin(t).*sin(t); plot(x,y); 复制 2. 含多个输入参数的plot函数 plot函数可以包含若干组向量对,每一组可以绘制出一条曲线。
l2 = plot(Ddtw); l3 = plot(Dmdtw); l4 = plot(Dnmse); leg1 = legend([l2,l3,l4],'DTW','MDTW','NMSE'); 定义图注时,调节句柄的顺序,可以调节图注中各个曲线的显示顺序。 添加横纵轴标签 xlabel('X-axis (m)','fontsize',16) ylabel('Y-axis (m)','fontsize',16) zlabel('Z-axis ...
The xlabel, ylabel functions are used to label the x and y axes. The usage of this function is as follows.xlabel('string'): Indicates labeling the x-axis in the current axis object.ylabel('string'): Indicates labeling the y-axis in the current axis object.Label the function image with ...
If Y is complex, plot(Y) is equivalent to plot(real(Y),imag(Y)). In all other uses of plot, the imaginary part is ignored. Various line types, plot symbols and colors may be obtained with plot(X,Y,S) where S is a character string made from one element ...

You can do something like the following, but you have a large number of ticks here... so
Plot 是绘制一维曲线的基本函数,但在使用此函数之前,我们需先定义曲线上每一点的x及y座标。下例可画出一条正弦曲线: close all; %linspace(5,100,20)和5:5:100的区别在于前者已知元素总个数而不知道步长,后者已知步长不知元素个数,这两者的效果是一样的 ...
