Little help with my apex

[snowmansnow]

I have the orange lable apex unit.
Recently I've noticed that the Temp and PH probes send and display, however there is no graph associated with it. Is there a place i'm missing to turn graphing on and off?
I've been looking a while and cant seem to uncover it.
Thanks,

Mine stopped recording on the graph when the time change happened. I unplugged everything from the wall so that the head unit powered all the way down, plugged it back in and it worked fine again, didn't have to reset anything. While I was trying to trouble shoot my logging issues, I cam across a lot of posts talking about the SD cards inside the apex going bad from too many reed/write cycles. So if powering it all down doesn't work that may be something to look into, but then you have to reprogram everything.
