Why Isn’t One of Plots Shown?
1 ビュー (過去 30 日間)
I have some questions regarding the code below
hax1 = axes('OuterPosition', [0 0 0.5 0.5]);
hax2 = axes('OuterPosition', [0.5 0.5 0.5 0.5]);
p1 = plot(1:10,rand(1,10), 'Color', 'b', 'parent', hax1)
p2 = plot(1:10,rand(1,10), 'Color', 'r', 'parent', hax1)
- Why isn’t p1 shown in hax1, although hold is on and both belong to hax1?
- How can I show both p1 and p2 on hax1? (I want to have p1 and p2 in separate lines and not in one line together (i.e., plot(x1,y1,x23) ,y2))
- Is there any way to specify a plot’s parent before plotting it? In the code above, I specified plots parents after entering the x and y coordinates, but I first want to specify plots parents and then later specify plots coordinates.

You need to use
hold( hax1, 'on' )
Every axes-related instruction you give should be to an explicit axes handle. Never just rely on the current axes otherwise you end up with issues like this.
Also I tend to use
plot( hax1, ... )
but it amounts to the same thing as what you did, it is all one single instruction so it isn't really after supplying the coordinates.
