Matlab Plot 使用多个图例( legend )

标签：matlab

     用matlab 画图时，发现线太多，生成的图例，遮盖了曲线。于是想画成多个图例，然后可以自由拖动。

     废话不多说，1）代码； 2）效果。

%%%%%%%%%%%%  Code:

figure
%% ---- plot for maxtries performance
set(0,'DefaultTextFontName','Times',...
    'DefaultTextFontSize',16,...
    'DefaultAxesFontName','Times',...
    'DefaultAxesFontSize',12,...
    'DefaultLineLineWidth',1,...
    'DefaultLineMarkerSize',6);
% set(gcf,'Units','inches','Position',[0 0 6.0 4.0]);

% ======================= trace_1:
% --- 1 UB_ratio_EMF_10_A_trace_1
h10_1_tr1=plot(X_items, UB_ratio_EMF_10_A_trace_1, '-pk');
hold on
% --- 2 Real Ratio
h10_2_tr1=plot(X_items, Ratio_EMF_10_over_OPT_trace_1, '-.or');
hold on
h10_3_tr1=plot(X_items, LB_ratio_EMF_10_A_trace_1, '-^b');
hold on
% ======================= trace_1:~

% ======================= trace_2:
% --- 1 UB_ratio_EMF_10_A_trace_2
h10_1_tr2=plot(X_items, UB_ratio_EMF_10_A_trace_2, '-+k');
hold on
% --- 2 Real Ratio
h10_2_tr2=plot(X_items, Ratio_EMF_10_over_OPT_trace_2, '-.dr');
hold on
h10_3_tr2=plot(X_items, LB_ratio_EMF_10_A_trace_2, '->b');
hold on
% ======================= trace_2:~

% ======================= trace_3:
% --- 1 UB_ratio_EMF_10_A_trace_3
h10_1_tr3=plot(X_items, UB_ratio_EMF_10_A_trace_3, '-xk');
hold on
% --- 2 Real Ratio
h10_2_tr3=plot(X_items, Ratio_EMF_10_over_OPT_trace_3, '-.sr');
hold on
h10_3_tr3=plot(X_items, LB_ratio_EMF_10_A_trace_3, '-<b');
hold on
% ======================= trace_3:~
