MATLAB:具有多个数据集的plottyy的图例 [英] MATLAB: legend for plotyy with multiple data sets
本文介绍了MATLAB:具有多个数据集的plottyy的图例的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我想根据压头的负载L自动创建样品的硬度H和杨氏模量E的图形.
I'd like to automatically create graphs of Hardness H and Young's modulus E of samples as function of load L of indenter.
我的目标是创建图例,其中包含标记为样本一的黑色圆圈标记,标记为样本二的黑色正方形等.
My goal is to create legend containing black circle marker labeled Sample one, black square labeled Sample two etc. Right now I get legend of default(blue) colour.
有.
这是我实际的MWE代码:
Here's my actual MWE code:
[m,n]=size(data1); %data1 - m x 3 matrix with data for first sample.
[ax,h1,h2]=plotyy([data1(1:m,1)],[data1(1:m,2)],[data1(1:m,1)],[data1(1:m,3)]);
%plots 1st sample data
set(h1,'linestyle','o')
set(h2,'linestyle','o')
c1=get(h1,'color);c2=get(h2,'color'); %store colors
line('parent',ax(1),'xdata','[data2(1:m,1)],'ydata',[data2(1:m,2)],...
'color',c1,'linestyle','s') %plots 2nd sample hardness
line('parent',ax(2),'xdata','[data2(1:m,1)],'ydata',[data2(1:m,3)],...
'color',c2,'linestyle','s') %plots 2nd sample young's modulus
感谢任何方法和/或纠正.
Thanks for any approach and/or correction.
推荐答案
如果您拥有每个不同元素之一的句柄,则可以将legend
与句柄向量和图例字符串单元格配合使用.
If you have the handle for one of each different elements, you can use legend
with a vector of handle and a cell of legend strings.
示例:
figure
hold all
for i=1:3
h(i) = plot([i i])
end
ylim([0 4])
legend([h([1 3])], {'aa', 'cc'})
