plot(x,sin(x),’r’) 5 用axis([xmin,xmax,ymin,ymax])函数来调整图轴的范围 axis([0,6,-1.5,1]) 6 MATLAB也可对图形加上各种注解与处理:(见上表) xlabel(‘x轴’); % x轴注解 ylabel(‘y轴’); % y轴注解 title(‘余弦函数’); % 图形标题 legend(‘y = cos(x)’); % 图形注解...
要进一步分别图像，我们需要给图像添加Legend，还要给整个图像命名，具体代码如下：To further separate the images, we need to add Legend to the image and also name the entire image as per the following code:x=0:0.1:5*pi y1=sin(x)y2=cos(x)plot(x,y1,'xr--',x,y2,'og:')legend('sin(...

MATLAB 中 legend 可以翻译为图例,下面逐一用例子来说明 legend 的用法,并辅以必要的说明。 我只挑选几种使用的来说明。 legend 在作图命令中(plot)给出图例标签; Plot two lines. Specify the legend labels during the plotting commands by setting the DisplayName property to the desired text. Then, add ...

This syntax allows the legend to show only the items listed in the subset. For example, if three curves are drawn, only two of them can be shown in the legend. Note that using this method requires assigning a plot to a specific variable. ...
