Crosshair axis

[Justace C. <pro...@co...>]

Does anybody know how I might get a crosshair axis setup with the tic marks on 
the axis that go through the origin?  Ya know, like if I walked up to a chalk 
board and drew and axis and then drew my function...

I looked at the various settings and did not see anything that would do it 
right.  I can see that I can remove the axis using the border command and 
then use the [x,y]zeroaxis commands but that does not actually move the axis 
with all the tics to the zero cross.

That's what you have commands like

	set xtics axis

for.  In total, the combination you're looking for would be something like

	unset border
	set xzeroaxis lt -1 lw .5 ; set yzeroaxis lt -1 lw .5
	set xtics axis ; set ytics axis
	plot sin(x)
