Increasing png "dpi"

[i***@gmail.com]

Is it possible to increase the size of the output, i.e. increase the resolution while keeping the relative line widths, text size etc at the same size? Use of .eps is not possible in this case.

Essentially I have been plotting with the default size and everything looks nice and balanced:

set term png

But for a large printed application I need a high dpi. When I change to:

set term png size 1200,800

or similar, the image does indeed get bigger but the line widths, point sizes etc all stay the same so when viewed at the same size as the original graph it is virtually unreadable - lines too thin, text too small.

So is there a way to increase to simply scale the png output to a high resolution?

No, you´d have to scale font size, point size, line width etc, accordingly.

But why can´t you use postscript or another vector format?
bitmaps are for web pages or very simple display units, who cannot
render svg graphics.

If you want to print it, you should definitely use either the postscript
or pdfcairo terminal.
