You may be wondering about the use of the COLUMN function for the third argument of
the VLOOKUP function. This function returns the column number of the cell that con-
tains the formula. This is a convenient way to avoid hard-coding the column to be re-
trieved and allows the same formula to be used in each column.
Row 25 contains formulas that calculate the difference between the two cities for each month. I used conditional
formatting to apply a different color background for the largest difference and the smallest difference.
The label above the month names is generated by a formula that refers to the DataTable cell and constructs a de-
scriptive title: The formula is
=”Average “ & LEFT(DataTable,LEN(DataTable)–4)
After completing the previous tasks, the final step — creating the actual chart — is a breeze. The line chart has
two data series and uses the data in A22:M24. The chart title is linked to cell B21. The data in A23:M24
changes, of course, whenever an OptionButton control is selected or a new city is selected from either of the
Data Validation lists.
