# Using gauge charts


Use gauge charts to compare values for items in a measure. You can compare them to another measure or to a custom amount.

A gauge chart is similar to a nondigital gauge, for example a gas gauge in an automobile. It displays how much there is of the thing you are measuring. In a gauge chart, this measurement can exist alone or in relation to another measurement. Each color section in a gauge chart represents one value. In the following example, we are comparing actual sales to the sales goal, and the gauge shows that we must sell an additional 33.27% to meet the goal.

To create a gauge chart, you need to use at least one measure. Put the measure in the **Value** field well. If you want to compare two measures, put the additional measure in the **Target value** field well. If you want to compare a single measure to a target value that isn't in your dataset, you can use a calculated field that contains a fixed value. 

You can choose a variety of formatting options for the gauge chart, including the following settings in **Format visual**.
+ ****Value displayed**** – Hide value, display actual value, or display a comparison of two values
+ ****Comparison method**** – Compare values as a percent, the actual difference between values, or difference as a percent
+ ****Axis style**** – 
  + **Show axis label** – Show or hide the axis label
  + **Range** – The numeric minimum and maximum range to display in the gauge chart
  + **Reserve padding (%)** – Added to the top of the range (target, actual value, or max)
+ ****Arc style**** – Degrees the arc displays (180° to 360°)
+ ****Thickness**** – Thickness of the arc (small, medial, or large)

## Creating a gauge chart


Use the following procedure to create a gauge chart.

**To create a gauge chart**

1. On the analysis page, choose **Visualize** on the tool bar.

1. Choose **Add** on the application bar, and then choose **Add visual**.

1. On the **Visual types** pane, choose the gauge chart icon.

1. From the **Fields list** pane, drag the fields that you want to use to the appropriate field wells. To create a gauge chart, drag a measure to the **Value** field well. To add a comparison value, drag a different measure to the **Target value** field well.
