Casio fx-5800p: Histogram

Casio fx-5800p: Histogram

The program HISTOGRAM draws a histogram for up to four data points using the Locate command.  The screen of the fx-5800p has 16 columns and 4 rows.   

When all four data points that are 15 or less, including 0, the histogram is exact.  If any data point exceeds 15, an approximate histogram is drawn as all the data points are normalized.  (Go to work with the limitations of the fx-5800p).  

Variables Used:
Data points: A, B, C, D
Normalized (if needed) data points: E, F, G, H
Sum: S = A + B + C + D



The example (shown above) shows a histogram with A = 10, B = 12, C = 13, D = 5
