i'm trying to superpose two graphic made by plot and boxplot functions. this is an example:
if true
% code
clear
%data
p=[0.9 1.1 1.9 2.1 2.9 3.1];
p1=[0.9 1.9 2.9];
p2=[1.1 2.1 3.1];
data1=rand(10,3);
data2=rand(10,3);
data=[0.4 0.2 0.5 0.6 0.7 0.9];
%boxplot
h1=boxplot(data1, 'positions', p1, 'labels', p1)
hold on
h2=boxplot(data2, 'positions', p2, 'labels', p2)
%box style
set(h2,'LineStyle','-.')
%plot
b=plot(p,data,'LineStyle',':')
%legend
legend('type1','type2','plot')
hold off
end
i have this message
if true
% codeWarning: Ignoring extra legend entries.

Hello, since boxplot returns more than one handler, you could use this to select only one of them:
legend([h1(1,1), h2(1,1), b], 'type1','type2','plot')
you can replace h1(1,1) with, h1(3,2) etc
Cheers
