Comparisons overlay prior periods or reference baselines to show change over time. Add multiple comparisons and configure labels, colors, and polarity.
CONTENTS
The Comparisons feature lets you overlay historical or reference data directly onto your charts.
It’s designed to show performance changes over time, such as year-over-year, month-over-month, or against a fixed baseline.
You can add multiple comparisons (e.g., “Comparison year 1”, “Comparison year 2”, etc.) to track trends across several periods at once.

Note:
Each comparison can be set to one of three modes:

How it works:
"Period over Period" compares your current selected timeframe with the immediately preceding period of the same length. It is a sequential look back in time.
The Multiplier:
You can use the Multiplier to decide how many period-steps to go back.
When to use it:
Best for short-term trend analysis to check immediate performance changes (e.g., week-over-week).
