Examples

Example #1 RRDGraph::setOptions example

<?php
$graphObj->setOptions(array(
    "--start" => "920804400",
    "--end" => 920808000,
    "--vertical-label" => "m/s",
    "DEF:myspeed=$rrdFile:speed:AVERAGE",
    "CDEF:realspeed=myspeed,1000,*",
    "LINE2:realspeed#FF0000"
));
?>

Example #2 Set multiple color options

<?php
$graphObj->setOptions(array(
    "--start" => "920804400",
    "--end" => 920808000,
    "--vertical-label" => "m/s",
    "--color=BACK#00000000",
    "--color=GRID#00000000",
    "--color=MGRID#00000000",
    "DEF:myspeed=$rrdFile:speed:AVERAGE",
    "CDEF:realspeed=myspeed,1000,*",
    "LINE2:realspeed#FF0000"
));
?>

Don't use key value syntax for same rrd option. It looks more readable, but it doesn't work. 

<?php
$graphObj->setOptions(array(
    "--color" => "BACK#00000000",
    "--color" => "GRID#00000000",
    "--color" => "MGRID#00000000"
));
?>

In nature of php it's same as 

<?php
$graphObj->setOptions(array(
    "--color" => "MGRID#00000000"
));
?>
