[Graph-dev] png options?

[Emile Aben]

Hi Daniel,

Thanks for the suggestion, I'm thinking of taking that a step
further and allow options for all terminal types that are 
supported (why treat eps and png different from the others ?)

You can expect syntax like:
{'output type' => 'png size 1000,600'} 
to work in a future release of Chart::Graph::Gnuplot (although
it might be a little while before we release a new version).

Btw. there is a 'size' option already in Chart::Graph::Gnuplot , did
you try that/had problems with it?

best regards,
Emile
