<p class=MsoNormal><font size=3 color=black face="Times New Roman"><span
lang=EN-CA style='font-size:12.0pt'>Hi AAron,<br>
<br>
The idea is that axes are always regular, so that the min, max and number of
steps is sufficient to generate the axis vector. The min and max is given in
the 'xylimits' field of Matlab data structure, or on '# xylimits:' line of
PGPLOT data format file. The number of steps is written in the 'type' field and
'# type:' line as well. Then that's really easy to generate the axes with
'linspace' function in Matlab.<br>
<br>
the best for you is to generate the data using the PGPLOT format. If you do not
have PGPLOT you will not be able to plot it. Anyway you may use the 'mcformat'
tool to convert it to e.g. Matlab format. You may also convert - still with mcformat
- your Matlab data into PGPLOT if the simulation is too long to re-run.<br>
