This outputs the pricing relationship of commodities in your data file,
as of DATE (optional), using the DOT language. If you have graphviz
installed, it can be viewed quite simply using:
ledger pricemap | dotty -
Each relationship in the graph shows the conversion factor to exchange
one commodity for another, and the date at which this factor was
determined.
It lets you specify a fixed cost for a duration of a ledger file, for
example:
fixed ecu $2
2008/01/01 income
assets🏦checking 1 ecu
income:salary
end fixed
This is equivalent to:
2008/01/01 income
assets🏦checking 1 ecu {=$2}
income:salary
