Analyzing Data with Pivot Tables 35
FIGURE 35.9
This pivot table shows sales by quarter and by year.
Grouping by time
Figure 35.10 shows a set of data in columns A:B. Each row is a reading from an instrument, taken at oneminute
intervals throughout an entire day. The table has 1,440 rows, each representing one minute. The
pivot table summarizes the data by hour.
ON the CD-ROM
This workbook, named hourly readings.xlsx, is available on the companion CD-ROM.
Following are the settings I used for this pivot table:
n
n
The values area has three instances of the Reading field. I used the Data Field Setting dialog box
(Summarize By tab) to summarize the first instance by Average, the second instance by Min, and
the third instance by Max.
The Time field is in the Row Labels section, and I used the Grouping dialog box to group by
Hours.
