#WOW2026 | 23 | Fun with Gantt Charts

Introduction

For the week’s challenge we’re looking at Gantt charts!

Gantt chart don’t have to necessarily show timeline data. In Tableau, they can be used to show “floating” bar charts. Which can be very powerful in certain use cases.

This challenge looks at historical American Football Super Bowl betting odds and game results. In this chart below, the arrow charts start at where the original gambling better line was, then the point of the arrow is the actual game result. The color of the line designates whether the actual result was over or under the betting line.

The O/U diff shows the normalized variance on a standard axis

Requirements

  • Dashboard size: 950×1500
  • Create a floating line bar chart on the left
  • Create a normalized variance bar chart on the right.
  • Match formatting as best as possible
