Hi,
as a short add-on - since you seem to use xmgrace for your plot:
Even if you just have the snapshot number as x-axis, you can simply
"transform" it to the appropriate time, since you know the conversion
factor.
For example, if you wrote snapshots every 10 ps, did not specify any
time information, but you want to present your plot in ns, in xmgrace
you open the 'Plot' ->' Axis properties' window, select the tab 'Tick
labels' and enter in the field 'Axis transform':
$t/100
where $t represents the variable for the actual axis value you like to
transform. So you can easily change the graph plot without changing the
input data.
Best regards,
Anselm
