Value mapping is a technique you can use to change how data appears in a visualization.
For each value mapping, set the following options:
- **Condition** - Choose what's mapped to the display text and (optionally) color:
- **Value** - Specific values
- **Range** - Numerical ranges
- **Regex** - Regular expressions
- **Special** - Special values like `Null`, `NaN` (not a number), or boolean values like `true` and `false`
- **Display text**
- **Color** (Optional)
- **Icon** (Canvas only)
To learn more, refer to [Configure value mappings](../../configure-value-mappings/).
