EDA Annotation Callout - Time Series Mechanics

Read the Callout

Start with three daily values. Tuesday has value 9 and the note promo day. The callout points to Tuesday. It explains the point, but it is not another data value. Read the chart as: Tuesday value is 9, and promo day is annotation text.

A tiny annotation readout: identify a callout marker, then keep the data value separate from the annotation text.

Start with data and notes

Start with 3 pinned rows and one note.

\text{data plus note}

Name the callout

The callout text belongs to the Tuesday point.

\text{callout belongs to point}

Read the marked point

Read the marked point: Tuesday has value 9 and callout promo day.

\text{marked point}

Separate value from note

Keep the value and annotation separate: promo day is a note, not another value.

\text{annotation is not value}
