Hi all,
I would like to create a plot object. I mean, to use the drawn plot for future uses along the same script.
For example I have the following line:
lineh=plot(x,y,'-rd','LineWidth',1.5);
x and y are series of values. This command generates a line depending on the values of x and y. I would like to keep this line in an object in order to draw it again at the end of the script. Is it possible?
Thanks in advance.
Raúl.

AFAIK: Something like
lineh.plot
is not possible. However, define a function handle
line_fh = @() plot(x,y,'-rd','LineWidth',1.5);
now the command
line_fh()
will produce the same plot each time. Or define
line_fh = @(x,y) plot(x,y,'-rd','LineWidth',1.5);
now the command
line_fh(x1,y1)
will produce the "same" plot with the values, (x1,y1)

See:
doc hold
lineh = plot(x,y,'-rd','LineWidth',1.5);
hold on
lineh2 = plot(x,rand(size(x),'-rd','LineWidth',1.5);

Thanks for the answer, Jan. I was looking for re-using the object 'lineh'. I mean draw 'lineh' at the end of the script for example. Able of drawing the same line by calling the object 'lineh'. I don't know if it was clear.

Perhaps you mean:
lineh = plot(x,y,'-rd','LineWidth',1.5);
pause(2);
set(lineh, 'YData', y + 0.5);
