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".) Allin Cottrell.
