MATLAB: Plot with ‘DisplayName’ in for loop

dynamiclegendplot

Hi, I am having trouble using plot with legend. I am trying to plot legend dynamically inside for loop. It is supposed to print 7 legend, since for loop goes from 1 to 7, but it only prints 6 legend. Do you see any problem in my code?
Here's my code.
 for k=1:7
    diffSum = 0;
    for 
       % inside for loop I calculate diffSum
    end
    legend('-DynamicLegend');
    plot(diffSum, 'color', rand(1,3), 'LineWidth', 3, 'DisplayName', sprintf('Group Thermal Comfort: %d', tc(k)));hold on;
    legend('show');
    drawnow;
 end
 hold off;

Best Answer

Put this line:
   legend('-DynamicLegend');
After the plot command. Like:
for k=1:7
    diffSum = 0;
    for 
       % inside for loop I calculate diffSum
    end
    plot(diffSum, 'color', rand(1,3), 'LineWidth', 3, 'DisplayName', sprintf('Group Thermal Comfort: %d', tc(k)));hold on;
    legend('-DynamicLegend');
    legend('show');
    drawnow;
 end
 hold off;
