Hello I have a 2d plot
where at vertical axis(Y) at a particular point say 0.0039 i want to draw a line parallel to X axis...
and in case of 3d plot I have to draw plane along vertical z axis at same point...
is matlab has any related function to do so....
actually what I want to do is http://s8.postimage.org/nyonm4hs5/fig.jpg in this figure i need to draw a line at 3.9*10-3 horizontally ,how to do this? regards

In 3D you need three coordinates to determine a plane. Does "plane along the Z axis" mean "perpendiculare to Z axis"? You cannot orient a plane along a line in 3D.

x=0.0039
plot([-10 10],[x x])

Ok Simon
x=0.0039
plot([[-10 10],[x x])
I was confused by "vertical axis(Y)"

Or use
y=0.0039
xlim=get(gca,'xlim')
plot(xlim,[y y])

How do you want to display the plane? An opaque SURF object will most likely hide all interesting details of the plot. What about a semi-transparent SURF object with an opaque border? Or a disc? Or a bunch of points?
