How to display the state variable in a graphic?

In simulink, when you have a graphic with many variables curves, how do you can distinguish one variable from another?

You can use “plot(___,Name,Value)” which is used to distinguish one variable from another.

This specifies line properties using one or more Name,Value pair arguments. For a list of properties, see Line Properties[AV1] [AM2] . Use this option with any of the input argument combinations in the previous syntaxes. Name-value pair settings apply to all the lines plotted.

For better understanding you can refer to following example:

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;

hope it helps !
