每次迭代后添加到图例

问题描述

我跑步

loglog(x,y);
legend('First script');

从第一个脚本开始.然后，hold on;.我运行类似的第二个脚本.我可以正确看到两个图形，但只能看到初始图例.我想从不同的脚本中增加图例.

from the first script.Then, hold on;.I run a similar second script.I see two graphs correctly, but only the initial legend.I want to increment the legend from different scripts.

如何从单个脚本添加到图例?

推荐答案

执行此操作的另一种可能的方法称为"DisplayName":

Another possible way to do this and it is called 'DisplayName':

hold all
for ind=1:3
x=[0:0.1:10];
plot(x, sin(x)+ind, 'DisplayName',['sin + ' num2str(ind)]);
end
legend(gca,'show')

从任何地方绘制到任何轴时都只需使用此属性:)

Just use this property when plotting from wherever to whatever axes :)

还有更多可能，例如动态图例！

There are even more things possible, like dynamic legend!

编辑

您必须在每次运行脚本后更新图例.您可以使用动态图例或仅通过legend('off')来完成此操作；图例(显示")

you have to update the legend after every run of a script. you can do this with the dynamic legend or by just legend('off'); legend('show')
