thanks, then I know I haven't overlooked something in the interface. I 
searched and found the Example 'l_u_fault' on bottom  
http://therion.speleo.sk/wiki/doku.php?id=metapost, which I should be able 
to 'misuse'.

But it dows not yield a dashed line (which would be perfect), but a thick, 
red line in the pdf output. This does not seem to be a problem of the 
matepost code snippet, as the strata example above (second from bottom) 
yields the same red line.

Do you have, perhaps, any idea where this comes from? Is there something 
missing? I think I have seen somewhere something about legend entry 
modification, next step I will learn that.

This I will use until I could solve the 'red line' problem: A headless 
arrow with a point label, as you mentioned…

…here. It is good to see what others are doing to learn about good 
practice.

Thanks and best regards,
