Storytelling using Annotations in Power BI with xViz Visuals

by | Jul 6, 2020 | Multi Axes Chart

This blog is part of the Multi Axes Blog Series

Annotations provide context to enhance your storytelling experience with textual call outs and drive attention to important areas. Annotations help communicate one’s ideas effectively by drawing attention to the marked areas with different colored icons and arrows.

Use Cases

  1. Storytelling – Answer immediate questions as to what caused the dip or spike in sales
  2. Outlier detection – Highlight Areas or specific data points which need attention
  3. Printed reports – Cases where you need print reports, Annotations can guide users on how to interpret your visualization with questions or additional information

Types of annotations

  1. Datapoint Annotation
    These are annotations made on data points where users can reference or include the data points(categories + values) as part of their annotation.
    Note- The annotation will disappear if the data point is filtered out.

  2. Canvas Annotation
    These annotations are made on non-data elements of the chart i.e the chart background or plot area. The only difference from data point annotations is that you cannot reference any data values in these types of annotations. They are indicated with a different icon.
