Re: [Gnuplot-info] What is the meaning of the terminal variables?

[Thomas S. <t.s...@fz...>]

the variables
GPVAL_TERM_XMIN, GPVAL_TERM_XMAX,
GPVAL_TERM_YMIN, GPVAL_TERM_YMAX
give the corners of the graph in pixels.
(you need version 4.4)

together with the information in
GPVAL_X_MIN, GPVAL_X_MAX, ...
it should be easy to translate data point coordinates into
pixels and vice-versa.

the fact that there are no
GPVAL_TERM_ZMIN, GPVAL_TERM_ZMAX
variables indicates that the above variables are no meant
for 3d-plots.
