How to clear mpg data and chart

[Lug_Nut]

I think that if I just go back into the 2008 entries I put in, and edit them to change the dates and data to continue from where I left off with the 2001 data, that it will be OK.
I'll try it anyway.
<edit> That worked. I just edited the table entries with the 2001 data in the same reverse calendar order I first entered the 2008 data. The table re-sequenced by the new calandar date and the chart data points reflected the edited data. Now the calendar sequence in the table matches the chart sequence. I'm back on track, but I'll just have to wait until I get the intervening years' data entered to see the most recent 90 days.<end>
