Hi Arjen,
I have two pltcl: /usr/local/plplot_build_dir/utils/pltcl and
/usr/local/plplot/bin/pltcl, both the same size at 22,004 bytes.
MBPro:~ jb$ cd /usr/local/plplot_build_dir/examples/tcl
MBPro:tcl jb$ export PATH=/usr/local/plplot/lib:$PATH
MBPro:tcl jb$ /usr/local/plplot/bin/pltcl
pltcl> source x01
PLplot library version: 5.9.9
Plotting Options:
< 1> xwin X-Window (Xlib)
< 2> tk Tcl/TK Window
< 3> ps PostScript File (monochrome)
< 4> pscPostScript File (color)
< 5> xfig Fig file
< 6> null Null device
< 7> tkwin New tk driver
< 8> memUser-supplied memory device
< 9> svgScalable Vector Graphics (SVG 1.1)
<10> bmpqt Qt Windows bitmap driver
<11> jpgqt Qt jpg driver
<12> pngqt Qt png driver
<13> ppmqt Qt ppm driver
<14> tiffqt Qt tiff driver
<15> svgqt Qt SVG driver
<16> qtwidget Qt Widget
<17> epsqt Qt EPS driver
<18> pdfqt Qt PDF driver

<25> pngcairo Cairo PNG Driver
<26> memcairo Cairo Memory Driver
<27> extcairo Cairo External Context Driver
Enter device number or keyword: 16
Right after I hit Enter here, what I believe might be the Qtwidget window
appears as an empty black window (with a title bar) for about 1/10 second
before it disappears.
QColor::setRgb: RGB parameters out of range

If I select 4 (psc), a PS file is created of size 21,483 bytes but my PDF
viewer refuses to open it, reporting a non-specific PostScript error. If I run
x01c and output to PS, the file is 47,429 and opens OK (except that it is
rotated 90 degrees but that's another issue). Doing a file comparison of the PS
files, the Tcl file's first three lines look like this:
%!PS-Adobe-2.0 EPSF-2.0
%%BoundingBox: -429496697 -429496697 5090 -4484
%%%
whereas the first three lines of the C-generated PS look like this:
%!PS-Adobe-2.0 EPSF-2.0
%%BoundingBox: 44 44 580 738
%%
The Tcl file contains 344 nan's of which 64 are lines like this:
/Helvetica nan SF
and 62 * 4 nan's are in lines like this:
/Helvetica [nan nan nan nan 0 0] SF
That file does end in %%EOF which I think is a valid eof marker for PS.
The C-generated PS contains zero nan's.
I've attached the Tcl PS file but I don't know if the list server will allow
it, so I'll cc you and Alan.
When I select <2> or <7> from the device list after starting x01, the results
are the same as when running x01c which I have reported earlier.
