Error in the chart legend

Hello

Why do I have a bug in the legend?

Code:

for i=1:1:4
 w1=subplot(1,2,1);hold on;
  p(i)=plot( w1,TR,y,[znaki(i),rodzaj{i},kolor(i)]);
  legend(w1,'w1 ','w2 ','w3','w4');
end

That would be an error unless znaki is a character vector and rodzaj is a cell array of character vectors, and kolor is a character vector, such that the triple [znaki(i), rodzaj{i},kolor(i)] forms a linespec . Which is plausible looking at your graph.

I'm assuming that the triple does produce the line specs shown in the first 4 legend elements.

It looks like additional plotting is done elsewhere in your code. Try this if you only want the first 4 objects in your legend.

 w1=subplot(1,2,1);hold on;
 for i=1:1:4
    p(i)=plot( w1,TR,y,[znaki(i),rodzaj{i},kolor(i)]),'DisplayName', sprintf('w%d',i);
 end
 legend(p,'AutoUpdate ', 'off');
