Data Structures For Game Programmers

Graphical Demonstration 22-1
===============================================================================
This demonstration shows you the distribution graphs of up to 4 random numbers.

- You may enter up to 4 random number ranges on the left of the screen.
- Click on the "Theoretical Distribution" box to show the theoretical distribution
  of the numbers; ie: the graph you would expect to get given the 4 random ranges.
- Click on the "Actual Distribution" box to show the actual distribution of the
  numbers, generated by a number of calls to the rand() function.
- Edit the number in the "Random Trials" box to modify the number of times that 
  rand() is called for the actual distribution. You should notice that the
  higher this number is, the close the actual distribution is to the theoretical
  distribution.
- Use the "Current" box to move the vertical black line through the graph. The
  "Theoretical" and "Actual" percentage boxes will be updated for each value.
