Heatmap chart

A heat map is a graphical representation of data where the individual values contained in a matrix are represented as colors. The color for each matrix position is determined by the metrics aggregation.

For more information, see #UUID-c6e512f6-c787-a741-9172-ff5a6f482ec3_UUID-dbfecda5-3c62-8de0-99e8-e076285a12af.

The buckets aggregations determine what information is being retrieved from your data set.

Before you choose a buckets aggregation, specify if you are defining buckets for X or Y axis within a single chart or splitting into multiple charts. A multiple chart split must run before any other aggregations. When you split a chart, you can change if the splits are displayed in a row or a column by clicking the Rows | Columns selector.

This chart’s X and Y axis supports the following aggregations:

  • Date Histogram

  • Histogram

  • Range

  • Date Range

  • IPV4 Range

  • Terms

  • Filters

  • Significant Terms
