Before GUIs, crude scatter plots and histograms on TTYs
and IBM electronic typewriters were used with only the
symbols on the keyboard. Some were pretty decent and
effective.
Basioc charts can be done that way but usually they are
just produceed by print statements with no special charting
or plotting software. The earliest plotting software that I'm
aware of all used bitmap imaging to the dot matrix printers
of the time
I don't really want to dabble with graphics at this point
The point of the graphics libraries like gnuplot is that they
make it easier to produce real graphics than it is to try fancy
printing techniques.
I don't want to get into all the finery of using GUIs.
The plotting libraries can usually throw up a window for you.
It won't be a full GUI application just a floating window in
screen with a graph drawn in it. Check out the screenshots.
Alternatively they can save the image to a file which you
can display in any graopghics program or web browser
of your choice.
However, it seems as though there ought to be some
really simple set up to just produce a scatter plot.
Maybe I'm overestimating the difficulty.
One way to find out would be to try writing one yourself.
You could then make it available to the community.
Sounds like a useful project...
