New Comment:
There is no "count" parameter for rrd_graph(), and never has been.
The function expects exactly (no more, no less!) two parameters:
1. The filename
2. An array of options
The error message in the original bug report was misread. The error message was
complaining that an incorrect number of parameters (i.e, not 2) were passed to
the function.

i'm not complaining about the function itself, just the way it's documented, the count
option is not mentioned in documentation but if you don't use it in the script, it will print
out the warning and fail
i don't know how to explain this more clearly sorry :)

The example shows that a parameter is indeed missing, though I doubt that it should represent a
count of something.
@lonny is right - this warning describes that the count (number) of parameters passed to the
function is wrong.

greetings, to me it seems as mandatory because if i omit it, i will get
the error message, here is the sample function from code, i've commented
out the "working" code
function cgraphvg($source, $output, $start, $title) {
$RRD="/u01/storage/rrd/$source.rrd";
$options = array(
"--start", $start,
"--title=$title",
"--lower-limit=0",
"-w 600",
"-h 300",
"-X 0",
"DEF:a=$RRD:usedvg:AVERAGE",
"DEF:b=$RRD:freevg:AVERAGE",
"AREA:a#0000ff:used GB in VG",
"STACK:b#00ff00:free GB in VG"
);
#$ret=rrd_graph("/u01/storage/html/$output", $options,
count($options));
$ret=rrd_graph("/u01/storage/html/$output", $options);
if(! $ret) {
echo "Graph error:".rrd_error();
}
}
it's hard to debug as the rrd_error() function doesn't return any
relevant error (the output is empty)

I don't believe that message is that there is a missing "count" parameter. I
believe It is saying that the number of parameters passed into rrd_graph is wrong.
Though, I am also not seeing where this error is thrown from called from
rrd_graph.
Please provide a short test script so we can see what is causing this warning to
be thrown.
