Strange Graphs & export issue

[redlion]

hi,
i have been pleased to see an improvement in the graphs withing control centre however it seems to be throwing up some rather odd charts... it looks like its capturing current data and shows this on the far right hand side (its so small you can hardly see it) but it also looks like its picking up a reading from before the beginning of time.... also i have noted that when i export i do not select "units" but it saves them to the text file. The text file used for this covers a few months only ...

Hello,

which version of GCC do you use?
Can you post a screenshot from your data in the text file?
