Heatmap

A heatmap is a data visualization tool that displays data density or intensity through color variations in various monitoring and analysis scenarios, suitable for presenting data distribution in specific contexts.

Chart Configuration

For more details, refer to Chart Configuration.

Color

Gradient intervals:

  • Supports selecting a number of levels from 2 to 100, with a system default of 60.
  • Includes 4 gradient color schemes.
  • Supports custom maximum and minimum values. If not set, the system automatically calculates based on the maximum and minimum values of the returned data.

Supports selecting a number of levels from 2 to 5, with a system default of 5.

Time

This fixes the time range for the current chart's data query, unaffected by dashboard or other global time components. Once set, the chart directly displays the time you specified, such as [xx minutes], [xx hours], [xx days].

This is the calculation interval (interval) for the chart's data query.

  • Auto Alignment: When enabled, the query is dynamically adjusted based on the selected time range and aggregation interval, rounding the calculated interval up to the nearest whole number.
  • Specified Time: The query is executed according to the selected interval. If this conflicts with the "Maximum Return Points" setting, the interval will be adjusted based on "Time Range / Maximum Points" priority. Options include 10 seconds, 20 seconds, 30 seconds, 1 minute, 5 minutes, 10 minutes, 30 minutes, 1 hour, 6 hours, 12 hours, 1 day, 7 days, and 30 days.

This is the maximum number of data points per series. You can enter any integer between 2 and 1000. If not customized, the default maximum is 720 points.

Note

If the query range is too large based on the selected time interval and exceeds the maximum points, the interval will be calculated and rounded based on the maximum points before returning data.

Y-Axis

If calculating the Y-axis based on data, you can set the maximum value, minimum value, and number of buckets to determine how the heatmap data points are displayed.

  • Maximum Value: Defines the upper limit of the Y-axis data display range.
  • Minimum Value: Defines the lower limit of the Y-axis data display range.
  • Number of Buckets: Determines the granularity of data grouping.

After configuration, hover over a data point to view the generation time, quantity, and interval for each heat block.
