# Configure value mappings

In addition to field overrides, value mapping is a technique you can use to change how data appears in a visualization.

For example, the mapping applied in the following image causes the visualization to display the text `Cold`, `Good`, and `Hot` in blue, green, and red for ranges of temperatures rather than actual temperature values. Using value mappings this way can make data faster and easier to understand and interpret.

![Value mappings applied to a gauge visualization](/media/docs/grafana/panels-visualizations/screenshot-value-mappings-v10.4.png)

Value mappings bypass unit formatting set in the **Standard options** section of panel editor, like color or number of decimal places displayed. When value mappings are present in a panel, Grafana displays a summary of them in the **Value mappings** section of the editor panel.

## Supported visualizations

You can configure value mappings for the following visualizations:

{{< column-list >}}

- [Bar chart](ref:bar-chart)
- [Bar gauge](ref:bar-gauge)
- [Candlestick](ref:candlestick)
- [Canvas](ref:canvas)
- [Gauge](ref:gauge)
- [Geomap](ref:geomap)
- [Histogram](ref:histogram)
- [Pie chart](ref:pie-chart)
- [Stat](ref:stat)
- [State timeline](ref:state-timeline)
- [Status history](ref:status-history)
- [Table](ref:table)
- [Time series](ref:time-series)
- [Trend](ref:trend)

{{< /column-list >}}

## Types of value mappings

Grafana supports the following value mapping types:

### Value

A **Value** mapping maps specific values to text and a color. For example, you can configure a mapping so that all instances of the value `10` appear as **Perfection!** rather than the number. Use **Value** mapping when you want to format a single value.
![The value 10 mapped to the text Perfection!](/media/docs/grafana/panels-visualizations/screenshot-map-value-v10.4.png)

### Range

A **Range** mapping maps numerical ranges to text and a color. For example, if a value is within a certain range, you can configure a range value mapping to display **Low** or **High** rather than the number. Use **Range** mapping when you want to format multiple, continuous values.
![Ranges of numbers mapped to the text Low and High with colors yellow and red](/media/docs/grafana/panels-visualizations/screenshot-map-range-v10.4.png)

### Regex

A **Regex** mapping maps regular expressions to text and a color. For example, if a value is `www.example.com`, you can configure a regular expression value mapping so that Grafana displays **www** and truncates the domain. Use the **Regex** mapping when you want to format the text and color of a regular expression value.
![A regular expression used to truncate full URLs to the text wwww](/media/docs/grafana/panels-visualizations/screenshot-map-regex-v10.4.png)

### Special

A **Special** mapping maps special values like `Null`, `NaN` (not a number), and boolean values like `true` and `false` to text and color. For example, you can configure a special value mapping so that `null` values appear as **N/A**. Use the **Special** mapping when you want to format uncommon, boolean, or empty values.
![The value null mapped to the text N/A](/media/docs/grafana/panels-visualizations/screenshot-map-special-v10.4.png)

## Examples

Refer to the following examples to learn more about value mapping.

### Time series example

The following image shows a time series visualization with value mappings. Value mapping colors aren't applied to this visualization, but the display text is shown on the axis.

![Value mappings time series example](/static/img/docs/value-mappings/value-mappings-summary-example-8-0.png)

### Stat example

The following image shows a stat visualization with value mappings and text colors applied. You can hide the sparkline so it doesn't interfere with the values.

![Value mappings stat example](/static/img/docs/value-mappings/value-mappings-stat-example-8-0.png)

### Bar gauge example

The following image shows a bar gauge visualization with value mappings. Note that the value mapping colors are applied to the text, but not to the gauges.

![Value mappings bar gauge example](/static/img/docs/value-mappings/value-mappings-bar-gauge-example-8-0.png)

### Table example

The following image shows a table visualization with value mappings. If you want value mapping colors displayed on the table, then set the cell display mode to **Color text** or **Color background**.

![Value mappings table example](/static/img/docs/value-mappings/value-mappings-table-example-8-0.png)

## Add a value mapping

1. Navigate to the panel you want to update.
1. Hover over any part of the panel you want to work on to display the menu on the top right corner.
1. Click the menu and select **Edit**.
1. Scroll to the **Value mappings** section and expand it.
1. Click **Add value mappings**.
1. Click **Add a new mapping** and then select one of the following:
   - **Value** - Enter a single value to match.
   - **Range** - Enter the beginning and ending values of a range to match.
   - **Regex** - Enter a regular expression pattern to match.
   - **Special** - Select a special value to match.

1. (Optional) Enter display text.
1. (Optional) Set the color.
1. (Optional) Set an icon (canvas visualizations only).
1. Click **Update** to save the value mapping.

After you've added a mapping, the **Edit value mappings** button replaces the **Add value mappings** button. Click the edit button to add or update mappings.

1. Click **Save dashboard**.
1. Click **Back to dashboard** and then **Exit edit**.
