Doc #60125 [Fbk->NoF]: Incorrect OOP example for rrd graphs

Edit report at https://bugs.php.net/bug.php?id=60125&edit=1 ID: 60125 Updated by: frozenfire@php.net Reported by: jeff at freethoughtdesign dot com Summary: Incorrect OOP example for rrd graphs -Status: Feedback +Status: No Feedback Type: Documentation Problem Package: rrd Operating System: OS X PHP Version: Irrelevant Assigned To: frozenfire Block user comment: N Private report: N Previous Comments: ------------------------------------------------------------------------ [2011-12-04 01:28:30] frozenfire@php.net Could you please try changing your OOP version so that settings like "--slope- mode" have a value, instead of having the option as the value. For instance, use "--slope-mode" => true and "--full-size-mode" => true. The reason I ask this is that the code for setOption in the rrd extension source uses a particular method to figure out which style you're using, which may screw up when you switch back and forth. ------------------------------------------------------------------------ [2011-10-24 23:58:44] jeff at freethoughtdesign dot com Description: ------------ The OOP example (http://www.php.net/manual/en/rrd.examples-oop.php) suggests that options to the RRDGraph be set as key:value pairs, and that works for some options, but it did not work for --color options until I used the syntax found on the procedural example page here: http://www.php.net/manual/en/rrd.examples-procedural.php The key:value syntax makes a bit more sense to me, but either way it seems like it should be consistent. The following only partially worked - the color settings had no effect: <?php $img->setOptions( array( "--start" => time() - 3600, "--end" => time(), "--vertical-label" => "Watts", "--slope-mode", "--title" => "Power Usage", "--width" => "600", "--height" => "300", "--y-grid" => "100:5", "--units-exponent" => "0", "--full-size-mode", "--color" => "BACK#FAF8CC", "--color" => "CANVAS#6D7B8D", "--color" => "MGRID#00ff00", "--color" => "GRID#E8E8E8", "--color" => "FONT#153E7E", "--color" => "AXIS#00ff00", "--color" => "ARROW#00ff00", "--color" => "SHADEA#000000", "--color" => "SHADEB#000000", "DEF:Watt=$rrd_file:watts:AVERAGE", "CDEF:Low=Watt,0,1000,LIMIT", "CDEF:Mid=Watt,1000,2000,LIMIT", "CDEF:High=Watt,2000,3500,LIMIT", "CDEF:VHigh=Watt,3500,15000,LIMIT", "AREA:Low#00ff00:0-1000", "AREA:Mid#ffbf00:1000-2000", "AREA:High#FF0000:2000-3500", "AREA:VHigh#ffffff:> 3500\c", "COMMENT: \l", "GPRINT:Watt:LAST:Current\: %4.1lf Watts", "GPRINT:Watt:AVERAGE:Average\: %4.1lf Watts" ) ); ?> In this version, based on the syntax in the procedural example, the graph colors worked correctly: <?php $img->setOptions( array( "--start", time() - 3600, "--end", time(), "--vertical-label", "Watts", "--slope-mode", "--title", "Power Usage", "--width", "600", "--height", "300", "--y-grid", "100:5", "--units-exponent", "0", "--full-size-mode", "--color", "BACK#FAF8CC", "--color", "CANVAS#6D7B8D", "--color", "MGRID#00ff00", "--color", "GRID#E8E8E8", "--color", "FONT#153E7E", "--color", "AXIS#00ff00", "--color", "ARROW#00ff00", "--color", "SHADEA#000000", "--color", "SHADEB#000000", "DEF:Watt=$rrd_file:watts:AVERAGE", "CDEF:Low=Watt,0,1000,LIMIT", "CDEF:Mid=Watt,1000,2000,LIMIT", "CDEF:High=Watt,2000,3500,LIMIT", "CDEF:VHigh=Watt,3500,15000,LIMIT", "AREA:Low#00ff00:0-1000", "AREA:Mid#ffbf00:1000-2000", "AREA:High#FF0000:2000-3500", "AREA:VHigh#ffffff:> 3500\c", "COMMENT: \l", "GPRINT:Watt:LAST:Current\: %4.1lf Watts", "GPRINT:Watt:AVERAGE:Average\: %4.1lf Watts" ) ); ?> ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=60125&edit=1
