When you create a range of conditions for a theme, you must specify the distribution method. The following methods are available:
| Distribution method | Description |
|---|---|
| Equal | The difference between the high and low values is the same for every range. This method is easy to interpret and is useful for showing continuous data such as rainfall. |
| Standard Deviation | Features are placed in ranges based on how much their values vary from the mean. Infrastructure Studio calculates the mean and then adds or subtracts the standard deviation to or from the mean to create the ranges. |
| Quantile | Each range contains an equal number of features. This method is useful for showing data in which values are evenly distributed. |
| Jenks (Natural Breaks) | Ranges are based on natural groupings of data values. Features with similar values are grouped together. This method shows the natural groupings in the data. |
| Individual Values | Features are not grouped. This distribution is useful if values are not continuous, there is a fixed number of values, and many features have the same value. |
