But my point is that the user should not need to do all this extra work just to turn off the extra margin, without having to know the (usually reasonably good) default label positions in the interior of the axis. (Why would one want to turn off the extra margins? In my real application, the x-axis is a %tc variable and it adds way too much margin, presumably because the %tc variable measured in milliseconds are huge numbers, extending the axis into the next day.) h. -- +--- | Hiroyuki Kawakatsu | Business School, Dublin City University | Dublin 9, Ireland.
