Key Takeaways

• The Tornado has a few limitations that you should be aware of before using:
  • If there’s a legend value it should only have 2 distinct values
  • Each distinct category values is a separate bar with left or right parts
  • Alternatively, you can have two measure values and compare them without  a legend

This shows a Tornado  with two distinct values in the Legend property.

• Under the Format paintbrush there are several options for customizing the appearance of the Tornado.
• From the Data Colors section you can specify what color is used for each distinct value of the Legend.

• By changing the values in the X-Axis section you can manually adjust the scale used to display the values.

• In the Data Labels section you may find it useful the adjust the Text Size, Decimal Places, Display Units, Inside fill or Outside fill.
  • The Text Size will adjust the value labels that are appearing inside the Tornado
  • Decimal Places will allow you to adjust rounding of decimal points
  • Display Units was actually changed for the sample image above to show in Thousands as opposed to the default, which usually shows in Millions.
  • Using Inside fill will change the color of the value labels

• The Legend property allows you to adjust the Position, Title, Text size, Color, or Legend Name.

• Using the Group property you can adjust the color of the group label text.

• In addition to these properties you have a set of settings that appears on every visual to adjust the background color, add a border around the visual and lock the aspect ratio.
