Adding legend for iteration and if condition graph

Good day, I currently having problem in insert the legend to a graph. Basically this is my coding in plotting the graph. I am using the DisplayName but the legend is missing also. Is it any other ways to put the legend into my plot?

      title('Graph of behaviour against iteration');
      xlabel('iteration t');
      ylabel('behaviour value');
      if max_euc_dist<0.056
          plot(i,dataCopyS5(i,:),'g.','MarkerSize',4,'DisplayName','Normal');hold on
      else
          plot(i,dataCopyS5(i,:),'m+','MarkerSize',4,'DisplayName','Anomaly');hold on
      end

The graph cannot change to scatter plot as the size of dataCopyS5 is 1000x8. Hope that my problem faced can be solved. Thank you.

 Try this,

          title('Graph of behaviour against iteration');
          xlabel('iteration t');
          ylabel('behaviour value');
          if max_euc_dist<0.056
              h1=plot(i,dataCopyS5(i,:),'g.','MarkerSize',4);hold on
          else
              h2=plot(i,dataCopyS5(i,:),'m+','MarkerSize',4);hold on
          end
          legend([h1 h2],'Normal','Anomaly')
