Re^2: GD Graph

I did run the data extraction code and it returns the expected values from the database. No problem there.

When I print value of $projectname variable I get following (as expected)-

'RMG Escalation Management Tool','Dynamic Reconfiguration FY06 Initiative'

If I put this line -

$mygraph->set_legend('Dynamic reconfiguration FY06 Initiative','Rmg Escalation Management Tool');

The graph is generated.

However if I put this-

$mygraph->set_legend($projectname);

I get following err in server log

$projectname needs to be an ARRAY: `Methods $graph->set_legend(@legend_keys); Sets the keys for the legend. The elements of @legend_keys corresp +ond to the data sets as provided to plot(). If a key is undef or an empty string, the legend entry will be ski +pped.` [download] So `my @projectname = ('Dynamic reconfiguration FY06 Initiative','Rmg Escalation Management Tool');` and `$mygraph->set_legend(@projectname);` HTH.

Lesson learned, "Always Read The Docs" or RTFM and then when all else fails, read them again. After all, the author took the time to write them for you ;-) Walking the road to enlightenment... I found a penguin and a camel on the way..... Fancy a yourname@perl.me.uk? Just ask!!!	[reply]
