diagrams and statistics not working for old dates

[Don-Pedro]

I entered data of an old car I once possessed, this was in 2002. Now, when I take a look at the diagrams it shows the years from 1970 up to 2014, however there's nothing drawn inside. Also the year range 1970-2014 is illogical, it would be reasonable to offer only the ranges where some data is present (i.e. 2002-2003). The same ist valid for the statistics, I can see only empty data for 2013 and 14 (the car has long been sold, so in fact there is no data), but no data for 2002 when I used the car is printed. So, for old data the diagrams and statistic functions are rather useless, that's a pitty but maybe you could fix this?
