Heatmap

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

Chart Configuration

For more details, refer to Chart Configuration.

Color

Gradient Range:

  • You can choose a number of levels from 2 to 100, with the system default being 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.

You can choose a number of levels from 2 to 5, with the system default being 5.

Time

This fixes the time range for the current chart's data query, independent of dashboard or other global time components. Once set successfully, the current chart directly displays the time you set, 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 time interval, rounding the calculated time interval up to the nearest appropriate value.
  • Specify Time: Executes the query according to the selected interval. If it conflicts with the "Maximum Return Points", the interval will be adjusted first based on "Time Range / By Maximum Points". 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 point limit is 720.

Note

Based on the selected time interval, if the query range is too large and exceeds the maximum number of points, the interval will be calculated and rounded based on the maximum number of points to return data.

Y-Axis

If you choose to calculate the Y-axis based on data, you can determine the display of heatmap data points by setting the maximum value, minimum value, and number of buckets.

  • Maximum Value: Limits the maximum display range for Y-axis data.
  • Minimum Value: Limits the minimum display range for Y-axis data.
  • Number of Buckets: Determines the granularity of data grouping.

After configuration, hover over a data point to view the generation time, quantity, and range of each heatmap block.
