heatmap

Input Stack:
expr: TimeSeriesExpr
Output Stack:
StyleExpr

Plot the time series as a heatmap visualization. This is useful for displaying multiple time series with high cardinality where individual lines would be difficult to distinguish. The heatmap uses color intensity to represent the magnitude of values across time and series.

Heatmaps work best with data that has been grouped by a dimension that produces many series, such as grouping by node.

Parameters

  • expr: A time series expression, typically the result of a group-by operation that produces multiple series

Examples

Basic heatmap showing multiple series grouped by cluster:

Default
name,sps,:eq,
(,nf.cluster,),:by,
:heatmap
  • :by - Group data to create multiple series suitable for heatmap display
  • :percentiles-heatmap - Create heatmap from percentile distribution data
