I have this plot
And as you can see, there's this gap between the zero and the bottom of the plot, is it possible to move the plot down so the 0 is at the bottom?
回答1:
Yes, it is possible. Use:
set xyplane at 0
to remove the offset.
On older gnuplot, you may need to use:
set ticslevel 0
instead.
回答2:
I can't really test it without your data, but did you try to set the limits on the axis? if not set manually, octave sometimes takes liberties to shift the data.
