strange for useing ' legend'

Dear, I used the following code to draw a figure. But the 'legend' didn't work well .I have used similar code for all drawing figures ,only for one didn't work. Please give me a hand! I really appreciate your help!

Best! xinjie

% % clear clc linestr={'ko','y*','rh','bs','K-','y-','r-','b-','g-','k--p','b--o','y--s','g--*','r--d','g-.h','g-.p'}; % linestr={'k-o','b-s','y-*','g-d','r-h','k-.o','b-.s','y-.*','g-.d','r-.h','k--p','b--o','y--s','g--*','r--d','g-.h','g-.p'}; linewidth = 1.5; data1=importdata('test.txt'); Data1=data1(:,[1:3,5]); [M,N]=size(Data1); current=ones(M,1)*[0 0.3,0.5,1]; frequency=[1,5:5:50]'*ones(1,N); amplitude1=ones(size(Data1)).*(0.02).*25.4./1000; gap1=ones(size(Data1)).*(0.1).*25.4./1000;

a=[ 198.7269 79.7653 -0.1376 23.8147 158.7006 0.6516];

Y1=(a(1).*current.^2+a(2).*current+a(3))./(2.*pi^2.*frequency.*amplitude1)./(a(5).*gap1+a(6))+a(4);

h=figure(1); for i=1:4 plot(frequency,Data1(:,i),linestr{i},'linewidth',linewidth); hold on plot(frequency,Y1(:,i),linestr{i+4},'linewidth',linewidth);

end LegednStr={'0.0Amps Test','0.0Amps Simulation ','0.3Amps Test','0.3Amps Simulation ','0.5Amps Test','0.5Amps Simulation ','1.0Amps Test','1.0Amps Simulation '}; titlestr=''; xLabelStr='test1'; yLabelStr='test2'; figName='test1';

setPlot(xLabelStr, yLabelStr,titlestr, LegednStr, figName);

You should use the "Code" format button to make that readable.

With this syntax on legend settings, it is working ok.

close all; clear all;
...
    
... 
titlestr=''; xLabelStr='test1'; yLabelStr='test2'; figName='test1';
setPlot(xLabelStr, yLabelStr,titlestr, LegednStr, figName);
...
%====
function setPlot(xLabelStr, yLabelStr,titlestr, LegednStr, figName) 
% % fig setting % % instructions of the interface£º % % 

box off;grid on; 
xlabel(xLabelStr, 'fontsize', 14, 'fontweight', 'bold'); 
ylabel(yLabelStr, 'fontsize', 14, 'fontweight', 'bold'); 
title(titlestr, 'fontsize', 14, 'fontweight', 'bold'); 
legend(LegednStr);legend boxoff; set(legend,'FontSize',14); 
set(gca,'LineWidth',1.5,'FontSize',14); 
Position = [0 0 793*2/3 596*2/3]; set(gcf,'position',Position) 
saveas(gcf, figName,'jpg'); 
end
