Graph color -how to set charts with blue color---[ok]

A simple question:

How to make the chart display with blue but not default red?  

Of course this can be found in the book or other documents, but I would be very appreciated if anyone can tell me now.


Thanks very much!

boxclr => ??
你也不说是什么模块里的图表,难道让我们猜吗?
GD::Graph?
$graph->set( dclrs => [ qw(blue green whatever) ] );
Thanks very much! It is ok now.
