Creating a gauge chart

This example shows a pie chart set up to resemble a gauge. Although this chart displays a single value (entered in cell B15), it actually uses three data points (in C12:C14).

Cell B15 contains a formula that calculates the percent of goal:

= B13 / B12

As you enter new data in column B, the formulas display the current results.

Cell C12 consists of 50%, and that slice is hidden.

The other two slices are apportioned based on the value in cell B15. The formula in cell C13 is

= MIN (B15, 100%) / 2

This formula uses the MIN function to display the smaller of two values: either the value in cell C15 or 100%. It then divides this value by 2 because I'm only dealing with the visible half of the pie chart. Using the MIN function prevents the chart from displaying more than 100%.

The formula in cell C13, shown below, simply calculate the remaining part of the pie:

= 50% - C12

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

   1.   Select cells C12:C14 and create a pie chart.

   2.   Remove the legend.

   3.   In the popup menu choose the Format Data Series...:

In this dialog box select the Series Options tab, and change the Angle of first slice setting.

   4.   In the popup menu for the slice 50% choose the Format Data Point... to change the slice's Fill to No fill and Border Color to No Line:

You can then make any other adjustments to get the look you desire.
