Instructions:

This program displays graphs of Bonferonni and Shewhart Control Bands in real time. The graph redraws the data every five seconds.

Clicking update bounds will recalculate the bounds for the data. If you wish to examine a snapshot of data without the graph automatically refreshing, the button stop refresh pauses the graph and you can then zoom it in more detail using the mouse to select a rectangle.

After you finish examining the data, clicking start refresh will cause the program to continue updating the graph in real time. Another feature of the program is a warning notice that will pop up in the top right of the graph if any of the past five data sets are outside the control bounds.
