20 gnuplot6 4.3FEATURES INTRODUCED IN VERSION 4.0
New:
set title "Old" 0,-1
set data linespoints
plot 1 2 4 # horizontal line at y=1
TITLE = "New"
set title TITLE offset char 0, char -1
set style data linespoints
plot 1 linetype 2 pointtype 4
Another compatibility issue is the effect of the command set size outside when not in multiplot mode.
In earlier versions, the command set size , caused some terminals to change both the size
of the plot and the size of the canvas is was drawn on; other terminatls changed only the plot size. The
use of set size to change the canvas size is now deprecated.
Please see set size (p. 129), set term size (p. 19) and also the documentation for individual terminals.
