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 range:

  • You can choose a level count ranging 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 level count ranging from 2 to 5, with the system default being 5.

Time

This fixes the time range for the current chart's data query, unaffected by the dashboard or other global time components. Once set, the 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.

  • Automatic alignment: When enabled, the query will dynamically adjust based on the selected time range and aggregation time interval, rounding the calculation interval up to the nearest whole number.
  • Specified time: The query will be executed based on the selected interval. If it conflicts with the "Maximum Return Points", the interval will be adjusted based on "Time Range / Maximum Points". Includes 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 input any integer between 2 and 1000. If not customized, the default maximum is 720.

Note

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

Y-Axis

If you choose to calculate the Y-axis based on data, you can set the maximum value, minimum value, and bucket count to determine the display of heatmap data points.

  • Maximum value: Limits the maximum display range of Y-axis data
  • Minimum value: Limits the minimum display range of Y-axis data
  • Bucket count: Determines the granularity of data grouping

After setting, hover over the data points to view the generation time, quantity, and range of each heat block.
