MikroTik

so i got some probe with raw value keep=very long time, and created a chart for it. but every time i open the chart it begins displaying at the time i open it. but i want to see how it was a very long time ago...
this probably sounds like a newbie question well it is...lol

dude server is running on an rb433ah up in some mountain and i am using dude client
kind regards

which versions of the dude?

the rb433 was running the latest version of the dude as of a few days ago. and i am using 4.0beta2 as client

the disk was completely full on the RB i think that might have been the problem.
i am using a new board since the other one got hit by lighting a strike
its working now
