How do I plot lines with different line widths?

I want to do:
but the linewidth propery ends up applying to both lines. Do I have to use two plot functions with a hold on command to have line1 a different width than line2? Thanks.

To plot two lines with different line widths, you can use either of these approaches.
1. Return the two “Line” objects as an output argument from the “plot” function and then set the “LineWidth” property for each.
p = plot(x1,y1,x2,y2)
p(1).LineWidth = 5;
p(2).LineWidth = 10;
2. Use the “hold on” command to plot the two lines separately. Specify the line width by setting the “LineWidth” property a name-value pair.

Hi: You can use handles.
h = plot(x1,y1,x2,y2);

x = 1:.01:10;
y1 = sin(x);
y2 = cos(x);
p = plot(x,y1,x,y2)
Line width, specified as a positive value in points, where 1 point = 1/72 of an inch. If the line has markers, then the line width also affects the marker edges.
The line width cannot be thinner than the width of a pixel. If you set the line width to a value that is less than the width of a pixel on your system, the line displays as one pixel wide.
