The single campaign statistic now includes a trendline, as well as trend indicators. The trendline in grey color shows you the overall trend for the selected time span. The trend indicator on the top right corner of each chart shows you the trend calculated in percentage. A green label indicates a positive change, and a red label indicates a negative change.
Please note that trendlines in your charts start showing with a selected time frame of 30 days or more. At least 20 sales are needed for the given time frame to show trendlines and indicators in the sales and ACoS chart.
We will add this feature soon to the dashboard. Currently, the dashboard already shows a comparison indicator if you select the ‘Month to date’ range option.
