Private communication with David Park leads us to conclude that we  
are supposed to interpret "across" as left-to-right in the following  
bit of one-line help:

"Tick mark lengths are given as a fraction of the distance across the  
whole plot."

In other words, the lengths of ticks for both axes are to be  
specified as a fraction of the total horizontal extent, so a y-tick  
length of 1 would extend across to the far edge of the frame, and x- 
tick length of 1 would be equally long. That's what we see in  
exported plots, and that's what we see on screen, once we have  
resized the graphic (no matter how trivially) with the mouse. What we  
see on screen before resizing, however, is that the x-tick length is  
proportional to the vertical extent of the plot. These x-ticks jump  
to their correct (we presume) lengths the first time one resizes the  
graph with the mouse.

Which leads to this question: Is there a programmatic way to do the  
equivalent of resizing?

PS. I prepared a notebook demonstrating most of the above, but didn't  
feel it worth sending to MathGroup. Write me if interested.
