2025 Week 27 | Sigma: Can You Stay Safe This 4th of July?

Sigma, Workout Wednesday / By

Introduction

As we all prepare ourselves (and our dogs) for this weekend in the US, let’s be careful out there. I’ve been on a bit of a kick of perusing government websites for data lately, and I’ve been surprised at how easy it is to pull data on a number of topics. This week, I’m focused on fireworks-related injuries, and wanted to show off some of the static-visualization features Sigma has to offer.

Requirements

  1. Get your data
    • Workspaces / Workout Wednesday / 2025 / 2025W27 – Can you stay safe this 4th of July? / NEISS Firework Incidents / NEISS Firework Incidents
  2. Build your bar charts
    • Weight by Age Bin (Displayed as a Percent of Grand Total)
      • Create a new calculation to make any Age < 30 = True, otherwise False
      • Set the new calculation as the ‘Color’ option in the visualization
      • Customize colors as desired
    • Weight by Body Part (Displayed as a Percent of Grand Total)
      • Limit display values to the Top 10 by right clicking on the ‘Body Part’ in the Y-Axis > Transform > Limit Display Values
      • Create a new calculation to make any Body Part in (“Hand”, “Finger”, “Eyeball”, “Face”) = True, otherwise False
      • Set the new calculation as the ‘Color’ option in the visualization
      • Customize colors as desired
  3. Build your text boxes
    • There are a few ways you could do this, I chose to use calculated values for all the values highlighted in red by calculating them in the text boxes directly.
    • Top box
      • Created a KPI in the ‘Source’ tab called ‘Number of Incidents’ where the value was the Sum of Weight
      • Used the following formula in the textbox: [Number of Incidents/Sum of Weight]
    • Middle box
      • SumIf([Weight by Age Bins and Highlight Age/Weight (1)], [Weight by Age Bins and Highlight Age/Age] < 30) / Sum([Weight by Age Bins and Highlight Age/Weight (1)])
    • Bottom box
      • SumIf([% of Incidents by Body Part/Weight (1)], In([% of Incidents by Body Part/Body Part], “Hand”, “Finger”, “Eyeball”, “Face”)) / Sum([% of Incidents by Body Part/Weight (1)])
  4. Customize colors and format to taste
    • Recommend going to workbook settings and changing to dark mode
    • Recommend putting all the elements into a container to get them to feel unified
    • Recommend adding subtle dividers between each section to give it some breathing room
