[Orca-users] Re: Nothing plotted on the graphs

[sebastien.harnist at systor.com]

Thanks for the script, I tried it, but everything looks ok with the
files :((.
On the Graphs the date is ok too, but there's nothing displayed on
them. I really can't understand why. I looked for the read right, but
this is ok too. So the graphs are generated with the correct date and
time, but empty. The files are copied trhough a permanent ssh tunnel,
I don't think they could be alterated this way...
Any idea could help ;)

thanks

Sebastien
