Sorry, but this fix must be undone. Don't know why but the
correct parameter is "lambda1" again.
Sorry, I'm not sure I understand.
Perhaps this explanation will help: You found a genuine problem
with the Poisson graphing code, but the fix you suggested was not
correct: "lambda0" is never a valid parameter name, within the
context of the graphing code in calculator.c. My fix in CVS aimed
to ensure that gnuplot never expected to read "lambda0", but
always looked for "lambda1" or higher -- and, naturally, to ensure
that "lambda1" (or higher) is defined in the gnuplot source file.
(The "param1", "param2", etc. business is related to the
possibility of generating a sequence of distribution graphs -- for
example, Poisson graphs with lambda = 5, 7, 9, ... You can do
this by generating an initial distribution graph then clicking on
the graph window and selecting "Add another curve".)
