Could anyone help me how to overcome the error in the following code:

code:
x = linspace(0,10);
y1 = sin(x);
y2 = sin(0.9*x);
y3 = sin(0.8*x);
y4 = sin(0.7*x);
y5 = sin(0.6*x);
y6 = sin(0.5*x);
plot(x,y1,'DisplayName','sin(x)')
hold on
plot(x,y2,'DisplayName','sin(0.9x)')
plot(x,y3,'DisplayName','sin(0.8x)')
plot(x,y4,'DisplayName','sin(0.7x)')
plot(x,y5,'DisplayName','sin(0.6x)')
plot(x,y6,'DisplayName','sin(0.5x)')
hold off
lgd = legend;
lgd.NumColumns = 2;
when i run the code it displays the graph but it has no legend in it.Instead it display the error stating No public field NumColumns exists for class matlab.graphics.illustration.Legend.

Hi jaah navi,
To display the legend use
lgd = legend('show');
The property/method 'NumColumns' does not exist. What is the purpose of that command?
Kind regards,
Robert

That feature did not exist in your MATLAB release.
... When are you going to upgrade? You keep running into these kinds of problems.
