Returning Plot handle From a function.

Hi Guys,

I have a function called myFill which uses the following commands to plot two filled areas:

 f = fill(freqPoints,filledGood,goodColour,freqPoints,filledBad,badColour);
 set(f(1),'EdgeColor',goodEdge,'FaceAlpha',0.5,'EdgeAlpha',1)
 set(f(2),'EdgeColor',badEdge,'FaceAlpha',0.5,'EdgeAlpha',1)

I want to be able to add a line at a later point in my code so I know I need the handle to the plot. But when I try:

 [ax,f] = fill(...)

I get the error "To many output arguments."

Can someone tell me how to return a handle to the plot, which can be used to up date it with a new line, please. Thanks in advance.

Kind regards,

Tim.

H = myFill

f = fill(freqPoints,filledGood,goodColour,freqPoints,filledBad,badColour);
set(f(1),'EdgeColor',goodEdge,'FaceAlpha',0.5,'EdgeAlpha',1)
set(f(2),'EdgeColor',badEdge,'FaceAlpha',0.5,'EdgeAlpha',1)

THEN

H = gca

 end

Outside function:

 hold on
 H = plot(x,newLine)
 hold off

you don't use two output arguments, just

    h = fill()

If you want a handle to the current axes, you can just do

     ax = gca;

with the plot active.
