#3057 — How to obtain a larger png image size

When I type set term png size 4000,3000, set out "something.png" and plot 
something the image size is indeed increased to 4000x3000 but my plot is 
magnified too much, causing it to be cropped.

Are there "legal" and "forbidden" dimensions? Do they have to abide a specific 
ratio?

No, principally.

With gp5.0.1 and 4.6.6,

	set term png size 4000,3000
	set out "testhuge.png"; plot x; set out

works alright, even 5000,30000.

What version, OS etc. are you using?

A workaround might be to use the pngcairo terminal.

Gnuplot version 4.3 patch level 3.

Windows version 6.3.9600

Version 4.3 was an internal development label given
to the development branch of the source code during 
approximately the period 2007-2009.  If you are indeed
running a snapshot of that development branch, it might
have any number of bugs or bits of experimental code
that were removed or fixed before the next major release
(version 4.4 Nov 2009).

So I think the most useful advice is to upgrade to a newer,
released, version with documented behavior.

Hell. You are on windows 8 and using a six+ year old development version
of gnuplot? :-)


I'd recommend you get yourself the latest 5.0.1.
If you want to be sure old scripts work exactly like before, use 4.6.6
(4.6.7 has no windows binary). Going back to 4.4.4 or even 4.2.6 might
again lead into problems, e.g. with the old libglib binaries that are
probably causing of your current trouble.

5.0 changed the standard colours, and there are a few incompatible
syntax changes, which aren't hard to fix. Check the release notes.

Then maybe you should get back to whoever made that program, because we 
didn't.

4.3 would be a development version somewhere between 4.2 and 4.4 --- but 
that would never have a patch level other than zero.
