Hi,

I am running CVS gnuplot rebuild at begining April 08.

I noticed this on svg output and looking back over archived plots (done  
with 6 mth old cvs) I note that png seems exactly the same layout:

however I have a jpeg (prob cvs march 07) that has no left margin and the  
first letter of the longest label touches the box.

This one has a rather large left margin , is there a minimum default width  
at play here?

cf http://piments.com/panel/150tank-txI.jpeg
cf file://localhost/tmpd/img/panel/150tank-tx6.png

Looking over many outputs over this period of time I see many different  
behaviours. For example this svg which has zero top and left margin but  
reasonable right and bottom. This has not explicit key commands in the  
source file.

Feel free to parouse http://piments.com/panel and  
http://piments.com/panel/images there are a variety of output formats  
dating from this period. All the 150tank* files are essentially the same  
gnuplot source as far as the box goes. There are a number of different  
plot titles in plot commands , none of which have any leading spaces.

The only key commands are:

set key box
set key top right
