Exemplos

Exemplo #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"
));
?>

Exemplo #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"
));
?>
