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(...
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. (4) legend(target, ) 若一个图窗中包含好几块...
1 首先，我们创建六条曲线，分两次绘制曲线x = 0 : 0.01 : 4*pi;y1 = sin(x);y2 = cos(x);y3 = 3*cos(x);y4 = cos(x).*sin(x);y5 = cos(x) + sin(x);y6 = cos(x) - 2*sin(x);h1 = plot(x,y1,x,y2,x,y3);hold onh2 = plot(x,y4,x,y5,x,y6);2 画出来的...
Plot two lines and add a legend to the current axes. Specify the legend labels as input arguments to the legend function. Get x = linspace(0,pi); y1 = cos(x); plot(x,y1) hold on y2 = cos(2*x); plot(x,y2) legend('cos(x)','cos(2x)') If you add or delete a data ...
Add legend for a specific plot. Learn more about legend, plot, cell array, function, curve fitting MATLAB
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 a legend. 画两条线。 通过将DisplayName属性设置为所需文本,在绘图命令期间指定图例标签。 然后,添加一个图例(legend)。
plot(x,y2,'og:'); hold off 3. 添加Legend和Title Add Legend and Title 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...
