Map Monthly Production Chart Years tab

The Years tab sets the extents of the X axis

Automatic - This option sets automatic scaling for the X axis of the production chart to the first and last month of production.  

Manual - These entries set limits on the duration of production data.  By default, Petra displays data from 1900 through 2100, which will be much too big a range for most applications.

Include Historical Production in Manual Mode - Some states record historical production in a single historical year labeled "0."  This option includes this historical year 0 in when years are set manually.
