Creating a twin or double thermometer chart

Excel 365
The thermometer chart displays the percentage of a task that's completed. See also how to create a simple thermometer chart, and how to create a glossy thermometer chart. But sometimes it will be more informative to display two results in one chart. This tip is how to create a thermometer chart with two competitive columns.

For example, the worksheet contains data from two teams to track monthly progress towards the goal: 1,000 new sales during the year. Cells C17 and D17 contain the goal value, and cells C19 and D19 contain a simple sum formula:

Twin or double thermometer chart data in Excel 2016

C19: =SUM(C5:C16) and D19: =SUM(D5:D16)

Cells C21 and D21 contain a formula that calculates the percent of goal:

C21: =C19/C17 and D21: =D19/D17

As you enter new data in column C or D, the formulas display the current results.

To create the chart like this one, do the following:

   1.   Select cells C21 and D21, if you want to create a percentage axis or select cells C17, C19 and D19, if you want to create an volume axis.

   2.   On the Insert tab, in the Charts group, choose the Column button:
