 When styling a vector layer, you can customize your data by property, such as size and color.
 For each property, you can specify whether to use a constant or data driven value for the style.

-This button is only available when vector features contain numeric properties.
+Use data driven styling to symbolize features by property values.
+To enable data driven styling for a style property, change the selected value from *Fixed* or *Solid* to *By value*.

+The *kibana_sample_data_logs* layer uses data driven styling for fill color and symbol size style properties.

+* The `hour_of_day` property determines the fill color for each feature based on where the value fits on a linear scale.
+Light green circles symbolize documents that occur earlier in the day, and dark green circles symbolize documents that occur later in the day.

+==== Quantitative data driven styling
+
+Quantitative data driven styling symbolizes features from a range of numeric property values.
+
+To ensure symbolization is consistent as you pan, zoom, and filter your map, quantitative data driven styling uses {ref}/search-aggregations-metrics-extendedstats-aggregation.html[extended_stats aggregation] to retrieve statistical metadata.
+
+Click image:maps/images/gear_icon.png[] to configure extended_stats. Set *Sigma* to a smaller value to minimize outliers by moving the symbolization range minimum and maximum closer to the averge. Clear the *Calculate range from indices* checkbox to turn off the extended_stats aggregation request.
+
+NOTE: When *Calculate range from indices* checkbox is cleared, symbolization may be inconsistent as users pan, zoom, and filter the map. Without extended_stats, the symbolization range is calulated from local layer data. The symbolization range is re-calulcated when layer data changes.

-Smaller circles symbolize documents with smaller payloads, and larger circles symbolize documents with larger payloads.
+Qualitative data driven styling symbolizes non-numeric properties like strings and ip addresses by category.
+
+Qualitative data driven styling is available for the following styling properties:

+* *Border color*
+* *Label color*
+* *Label border color*
+
+Qualitative data driven styling uses {ref}/search-aggregations-bucket-terms-aggregation.html[terms aggregation] to retrieve the top nine categories for the property. Feature values within the top categories set are assigned a unique color. Feature values outside of the top categories set are grouped into the *Other* category. A feature is assigned the *Other* category when the property value is undefined.
