Sorry, there was a problem processing your log
Your log is missing the important FMT Data
Logs from different autopilots and different versions of ArduPilot contain slightly different data.
At the start of your dataflash log ArduPlotter expects there to be some lines that describe the actual data in the log. These lines are known as 'FMT' data.
Without this 'FMT' data ArduPlotter cannot work out what the data within your log actually means, as it just sees just a bunch of numbers.
If you have deliberately removed these lines please re-add them and then re-upload your log to be able to see all of your pretty data!
But my log does have FMT data?!
If this is the case, and you can see FMT data in your log when you open it in a text editor, please contact Chris, as something has gone horribly wrong!
FMT data will look something like the example below, and should be at the very top of your log file
FMT, 128, 89, FMT, BBnNZ, Type,Length,Name,Format,Columns FMT, 129, 23, PARM, Nf, Name,Value FMT, 130, 45, GPS, BIHBcLLeeEefI, Status,TimeMS,Week,NSats,HDop,Lat,Lng,RelAlt,Alt,Spd,GCrs,VZ,T
