Is this the correct group for this? Anyway, a friend and I were playing with my new HP-28C calculator this weekend and played with the graphics a bit. After rearranging our program a bit, the result is one which will plot a histogram of any column of the statistics matrix. Put the column number on the stack and let it go. In the following, '$' means the sigma character. HIST: << -> c << PPAR 's' STO (1,0) PMIN N$ MAX$ R->C PMAX CLLCD 1 N$ FOR i i 0 '$DAT' i c 2 ->LIST GET FOR y DUP y R->C PIXEL NEXT DROP NEXT s 'PPAR' STO 's' PURGE >> >> Great fun!!
