Hello, my legend color doesn't match the color of my plot. I need two diffentent colors in my legend. I have already searched the other questions asked, but none of them seem to work for me.
figure
hold on
% P(1) = plot(x1,a1,'g.',x2,b1,'g.',x3,c1,'g.',x4,d1,'g.','DisplayName','a')
plot(x1,a1,'g.',x2,b1,'g.',x3,c1,'g.',x4,d1,'g.');
errH1 = errorbar(mean(x1), mean(a1), error_LG(1,Rauheitskennwert),'g+');
errH1.LineWidth = 1.2;
errH2 = errorbar(mean(x2), mean(b1), error_LS(1,Rauheitskennwert),'g+');
errH2.LineWidth = 1.2;
errH3 = errorbar(mean(x3), mean(c1), error_LgR(1,Rauheitskennwert),'g+');
errH3.LineWidth = 1.2;
errH4 = errorbar(mean(x4), mean(d1), error_RG(1,Rauheitskennwert),'g+');
errH4.LineWidth = 1.2;
xlim([0.5 4.5])
plot(x1,a_Filter,'.b',x2,b_Filter,'.b',x3,c_Filter,'.b',x4,d_Filter,'.b');
% P(2) = plot(3,a_Filter,'.b',3,b_Filter,'.b',3,c_Filter,'.b',3,d_Filter,'.b','DisplayName','b')
errH6 = errorbar(mean(x1), mean(a_Filter), std(a_Filter),'b+');
errH6.LineWidth = 1.2;
errH7 = errorbar(mean(x2), mean(b_Filter), std(b_Filter),'b+');
errH7.LineWidth = 1.2;
errH8 = errorbar(mean(x3), mean(c_Filter), std(c_Filter),'b+');
errH8.LineWidth = 1.2;
errH9 = errorbar(mean(x4), mean(d_Filter), std(d_Filter),'b+');
errH9.LineWidth = 1.2;
% legendNames = ['a','b'];
% legend(P)
legend('a','b')

You did not explicitly state the handles for the legend, so Matlab uses the first two, which happen to be both green, since your plot call returns 4 objects.
%these are the required edits:
h_green=plot(x1,a1,'g.',x2,b1,'g.',x3,c1,'g.',x4,d1,'g.');
h_blue=plot(x1,a_Filter,'.b',x2,b_Filter,'.b',x3,c_Filter,'.b',x4,d_Filter,'.b');
legend([h_green(1) h_blue(1)],{'a','b'})
