[Graph-dev] png options?

[Steinar Midtskogen]

Hello,

First, sorry for replying to a nearly 5 years old message, which I
found in the archive.  It is also the last message to receive a reply,
so perhaps Chart::Graph::Gnuplot development is dead?

I wish to use svg, but "output type" doesn't accept arguments.  Only
eps does.  I would like to set the svg size.  The "size" option in
Chart::Graph::Gnuplot will only work to make the size smaller, not
bigger, which will cause the graph to become clipped.

Any chance that there will be an update?
