Macro SheetProcessor draws autocorrelograms and time-based-average charts.
Autocorrelograms indicate the presence or absence of periodicity. Time-based-average charts indicate the average of the data values by the time of day.
Run macro SheetProcessor after designating variables and evaluation time in the light-green cells in the B column.
Designate the evaluation period and data types using the drop-down menu.
The evaluation time is 12 hours at maximum. Longer time than this renders the analysis meaningless.
Irrelevant to the designation, the evaluation times of HGT and SUTD are 0 and the data time interval, respectively, for the following reasons.
The variable HGT stands for the momental height value at each data sampling by definition.
The evaluation time of SUTD matches with the data time interval by definition.
Instead of average values, time-based-average charts for VNF and VNI gives the toal number of data available at each time.
to check how evenly or unevenly data are distributed.
The date values in cells "D1" and "G1" determines the period for analysis.
Choose periods suggestive of periodicity by refering to the charts in the TL and TS sheets.
The analysis period needs a certain length of time. The period of 12 days may be the minimum.
Rerun the macro SheetProcessor after changing the designation.
