[Gnuplot-info] Grayscale PDF from Qt

[Elias A. <eli...@gm...>]

Hi,

I love the new feature that lets me save a PDF directly from the wxt / 
qt terminal.  However, from Qt I get grayscale PDFs (SVG/PNG from Qt and 
all formats from wxt are in color).

In this thread 
<http://gnuplot.10905.n7.nabble.com/Proposal-Saving-graphs-from-Qt-and-wxt-terminals-td18874.html>, 
somebody had the same problem but then: “The color is working for me 
now.  I'm not sure what happened.”  Whatever it was, it has not happened 
for me yet.

Does anybody know what needs to happen to get the color PDFs?

Granted, it is not a big issue in practice, I could just revert to wxt …

Hi,

maybe you can give us some more information on how you plot and save.
Do you change the term settings?

I am running Gnuplot with Version 4.6 patchlevel 6 (last modified September 2014) [Archlinux package: gnuplot 4.6.6.1].
The default settings after freshly starting gnuplot result in colored pdf files, when saving right from the gaphic dialog.

Cheers,

I do not.  I am using gnuplot 5.0.0 compiled against Qt5 (sorry I did 
not mention this originally).  Just starting gnuplot and, e.g.,

 > gnuplot-5.0

	G N U P L O T
	Version 5.0 patchlevel 0    last modified 2015-01-01

	Copyright (C) 1986-1993, 1998, 2004, 2007-2015

	gnuplot home:     http://www.gnuplot.info
	faq, bugs, etc:   type "help FAQ"
	immediate help:   type "help"  (plot window: hit 'h')

Terminal type set to 'qt'
gnuplot> p sin(x)

and clicking “Export to PDF” results in a grayscale PDF.

I just built 5.0.0 against qt4--I couldn't figure out how to get it to
build against qt5--on linux and can confirm this behavior. The png and
svg saves are in full color, but the pdf is gray scaled.
