they all have the line defined in the gnuplot files, eg:
- Code: Select all
,'' using 1:($2-$2) with lines linetype 0 linewidth 1 linecolor rgb "#FFFFFF" title "" axis x1y1
$2-$2 is zero -- it uses the x coordinate and y=0
why do you think it is not there? it should be invisible. , that might not work. but if it is invisible you should not see it .
it purpose is not to draw a line, to force gnuplot to show the whole range selected.
sometimes when there is no data left or right, gnuplot does not show that part.
thats why it was added to plot a "fake" line at the x axis from left to right.
