Change Comparison Chart¶

The Change Comparison Chart is a data visualization component focused on presenting the dynamic changes of metrics. It can quantitatively compare the values of specified metrics in the current period with those from the same historical period (e.g., the same time yesterday, the same day last week), and intuitively display the magnitude of change, thereby quickly identifying abnormal fluctuations.

Use Cases¶

Track the growth rate of core business metrics (e.g., Daily Active Users) compared to yesterday/last week's same period;
Monitor changes in system metrics (e.g., CPU usage, memory usage) before and after a release;

Data Source Query

For more details, please refer to Chart Query.

Sort¶

You can choose to sort based on the change value, baseline value, or comparison value, ultimately returning the specified number of Top/Bottom entries from the query.

Baseline Value¶

Select the data value to be used as the reference point for comparison. The query Condition A is selected by default.

Comparison Value¶

Select the data values for the current and target time periods to be compared, including:

Other metrics

Absolute Change: Baseline Value - Past Baseline Value (selected by default)
Relative Change: (Baseline Value - Past Baseline Value) / Past Baseline Value * 100%

Legend¶

Supports choosing to hide the legend, or display it at the bottom or right;
You can choose whether to display the baseline value.
