Open Flash Chart

:: Home - Gallery - Y Axis - Legend

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 - Y Axis - Legend

Thanks to http://webbie.suppi.net/ressources.php?backgrounds for the art.

Method: set_y_legend()

set_y_legend( string $text[, int $size=-1][, string $colour=''] )

$text is the string to display.
$size (optional parameter) in pixels.
$colour (optional parameter) HEX colour string.

If you change the font size, the chart resizes to accommodate it. To remove the Y legend, don't call the set_y_legend() method.

Note Open Flash Chart has a known bug. The Y axis legend will not show unicode characters correctly. This seems to be a bug in flash its self.
