Hey guys,

1st of all, I need to say a sorry for my poor explanation in the post.

Re: dpb [Yeah, I knew plot() ignored NaN's which will give the extra point;
thought your intention was for the end tick label to be totally blank.]

Indeed, it was not clear from my post. Your hint will prove useful at some point later, I'm sure of it!

> > I mean I need to display a "zero line" in the plot.

I should have said, I need to get a horizontal zero line to the plot. Going through each bit of hints you gave, finally this worked in the code. (Guess after how many trials I came up with the right positions...)

line([xmin xmax], [0 0], 'Color', 'k');

Guys, a big thank you!
