Open Flash Chart

Info: Open Flash Chart 2 is out. Version 1.x and these pages will never disappear and the charts will continue working forever, but further development on 1.x has stopped. Take a look at version 2 here Open Flash Chart 2.

Gallery - Candle

Method: candle

candle( array $data, integer $alpha, integer $line_width, string $colour, [, string $text] [, integer $size] )

The data array must be an array of candle objects.

candle( integer $high, integer $open, integer $close, integer $low )

The candle object take four parameters, high, open, close and low. The candle is hollow if it opens higher than it closes.

Note:
The candle adds extra magic options to the tooltip string:

#high#
#open#
#low#
#close#

I assume you can figure out what those magic values get replaced with :-)

Create the flash object
