Doesn't deleting an object imply deleting its handle as well?

Do you mean delete the object but not the axes handle?

Do you mean make the object invisible on the axes?

Please clarify.

If you meant to keep the axes but delete the plot within, you could do
something like

> plotHandle = plot(x,y, ... )

then, to delete the plot
> delete(plotHandle)

The axes and figure objects will remain, but the plot will be removed.

However, as Nathan explained, you cannot delete an object w/o deleting
its handle.

You can use

cla

To clear your current axes. You can use

set(h,'visible','off')

to make your plot invisible, or use PATCH to cover the axes with a big white patch.

     CLA RESET deletes all objects (including ones with hidden handles)
     and also resets all axes properties, except Position and Units, to
     their default values.


If you do not want the properties reset,

delete(allchild(AXISHANDLE))

This might, however, end up recomputing various axis limits such as xlim if
their modes are set to auto, so you might want to hold(AXISHANDLE) before
doing the delete().


Note that -in general- you *do* want to delete objects with hidden handles
within an axis. For example, if you use polar(), then several of the created
graphical objects have hidden handles as they are not intended to be
manipulated independently.

thanks for your helpful answers.
