Charting. Run a 6 hour trace starting at midnight each day. When viewed on the Sky Pipe screen, this data file will show the full duration of the file on the screen divided into four segments, each approximately 1.5 hours long. Count the number of hits in each 1.5 hour segment. Make a chart for each day with the date along the y axis and the segment of time 1.5 hour bits recorded along the x axis. Put the day of the month in the left hand column and the number of hits in each segment along the x axis. Put this in an Excel or other spreadsheet if you wish, or graph the results on graph paper to show the variation from day to day, as shown below. Website note/; add a printable table that students can use to fill in their data.
