Segment out of the Graph

I tried setting ylim=(0, 1000) but the segment that I have draw is at y=-10 so if I set the y origin to 0 I don t have the segment, if a l leave it at -10 I have the segment but the axis start from -10. I would like to have both. So to have a graph with ylim=( 0, 1000) and under it a segment parallel to the x axis at -10.
If you really want that then you will need to look at the xpd parameter for par.
I am sorry it is contorted thing :) Claudio
If instead you want to plot at y= -10 without changing xpd, then set axes=FALSE in the plot command and then construct your x and y axes separately to your specifications. Any more specific comments will require that you present code (as well as a better description) that constructs an example.
