Please read `help colorspec` carefully.

This would be one valid option of many options:

green = "#00009600"
set title font "verdana,12" tc rgbcolor green "hits \\@ https://dataswamp.org/\\~$USER"

With the data available (and because the question is interesting), two
additional comments:

+ you may ease managing user-defined tics with exponential notation
  like e.g., in Fortran:

  ```
set format y "%.0f"
set ytics font "verdana,10" add \
              (  0         0, \
               "1M"  1e06, \
               "2M"  2e06, \
               "4M"  4e06, \
               "6M"  6e06, \
               "8M"  8e06, \
              "10M"  1e07, \
              "12M" 1.2e7, \
              "14M" 1.4e7)
   ```

+ gnuplot actually may add SI prefixes (k, M, etc.) on the scales for
  you and show user-defined tics.  For this to happen, drop "set
  format y "%.0f" to try instead

  ```
set format y '%.0s %c'

set ytics font "verdana,10" add \
("25 M"   2.5e7)  # only shown for the ordinate scaling by lg

set logscale y  # i.e., the implicit form of "set logscale y 10"
  ```

  The plot then retains an obvious hint something happened to
  "katzeilla" and "rjc" during the first interval of recording while
  the relative variation of the other traces was smaller.  Credit to
  stackoverflow user Christoph for the showcase[1] about the
  alternative format.

  Perhaps altogether with an instruction like "set yrange[1000:1e9]"
  this may justify to move/reorganize the keys a little bit.

Why doesn't this work and how should you put it?

  green = "#00009600"
  # ...
  set title font "verdana,12" tc green "hits \\@ https://dataswamp.org/\\~$USER"

It says the "colorspec option not recognized." at "green" on the last line.

How do you set the size of the numbers for the y-axis?

This

  set ylabel font "verdana,11"

doesn't seem to take.

set ytics add (0           0, \

Thanks for the explanation and example, I get it, but I'm not
getting it to work.

First, for me it says "decimal sign in locale is ." after
I set it to French; and after that it's still 14000000, i.e.
no grouping.

14M would be optimal IMO but 14 000 000 much better than
14000000 and "good enough for government work" I guess.

A correction, sorry. 
I meant to say the standard "C" local does not use a special character
for the thousands separator.  That is the default for gnuplot.
en_US locale uses a comma.  fr_FR uses a space.

The thousands separator format is sensitive to the current locale.
I do not know of any way to set is separately; only as one component
of a full numerical locale.  Standard US practice does not use a special
character for this purpose, so the standard US locale ignores the aposrophe
in a format.   Other locales do provide one, however.

Here is an example of how you can use this in gnuplot:
Script:

A = 1234567.89 

set decimal locale 'en_US.UTF-8' 
US = sprintf("%'.2f", A) 
print "US format is ", US 

set decimal locale 'fr_FR.UTF-8' 
FR = sprintf("%'.2f", A) 
print "FR format is ", FR
Output:

decimal_sign in locale is . 
decimal_sign in locale is , 
US format is  1,234,567.89 
FR format is  1 234 567,89

Grouping. Don't know if that's supported or why it doesn't

Not mentioned (?) but this:

e.g.

  $ numfmt --format="%.f" --round=nearest --to=si 123000000
  123M

I have a similar, long-standing problem if you have the time to consider 
it. I've done all the above and they work perfectly, with the exception 
of the "drag rectangle to define new zoom region". I've tried but never 
succeeded in changing that from its default dark blue color, which is 
almost invisible on a black background.

I believe I'm using the default "qt" terminal. It won't accept a 
"background" argument in `set terminal` so instead I've been doing:

     set object 1 rectangle from screen 0,0 to screen 1,1 fillcolor rgb 
"black" behind

The example code in the StackOverflow link you posted (thanks!) using 
`set terminal wxt ...` works better -- the rectangle is light-colored 
and visible -- but the text with the coordinates of the rectangle is 
still a dark color and unreadable.

Is there a way to change the color of all of these interactive 
mouse-feedback elements in addition to the plot graphics? Thanks in 
advance for any suggestions.

Please read and study the answer in detail to that linked question!
You can also read the docs.
In gnuplot console type: help borders, help xtics, etc..
One example hint: `set border lc "white"

You simply have to set the linecolor and textcolor of all the other objects, e.g. borders, labels, tics, etc. to "white".

Okay, cool, later tho - but this reminds me of another problem
which I got only at the gnuplot step, namely (ha) those
usernames are hard-coded! But they are known up until then so
how do I make gnuplot know about it as well, pass it to
gnuplot if you will?

As you see I've successfully set the background to gray,
a compromise where the black lines of everything else is
still visible.

However I'd like to set the background to black. I happens the
same way but how do I then set everything else to bright
color(s) so they are still visible?

This was once known as a bright-on-black theme, now it seems
it is called "dark mode".

But that's what I desire anyway :)

If you know how to achieve it?

On stackoverflow, user Christoph answers this with examples using the
exponential notation,[1] i.e.,

```
set format y '%.0tE%+T'
```

and one where (user defined) yticks' labels basically run by kB, MB,
GB, TB, PB.[2]  Though for the second one, gnuplot possibly offers a
more compact approach than by addition of 

```
set ytics 10
set mytics 10

set ytics add ( "1 kb" 1000, \
"10 kb" 10000, \
"100 kb" 100000,\
"1 mb" 1000000, \
"10 mb" 10000000,\
"100 mb" 100000000,\
"1 gb" 1000000000, \
"10 gb" 10000000000.0,\
"100 gb" 100000000000.0,\
"1 tb" 1000000000000.0, \
"10 tb" 10000000000000.0, \
"100 tb" 100000000000000.0, \
"1 pb" 1000000000000000.0, \
"10 pb" 10000000000000000.0 )
```

as instruction.

Based on the preview shared with simultaneous presence of lower-level
(trace rjc; incal and lich) and higher-level data (trace solene), a
plot substituting y by its transformation into lg(y) or sqrt(y) may be
worth a consideration.

Like "black", there is "white", i.e. an instruction like

```
set term pngcairo background rgb "white"
```

to expand all over the canvas*) equally is possible.

*) If your aim is to alter the representation only within the plot,
but not on the caption, legend, etc, you still could put a rectangle
behind (back) the plot.  As a verbose minimal working example:

```
set terminal pngcairo
set output "test.png"
set object 1 rect from graph 0, graph 0 to graph 1, graph 1 back
set object 1 rect fc rgb "gray" fillstyle solid 1.0
plot sin(x)
```

With regards

How do I get a bright-on-theme? I did 'set term png background
rgb 'black'' but then how do I do everything else bright?
