Starburst charts, sometimes called sunburst charts or circular timelines, are one method of displaying data over time. They may look cool, but they aren't exactly easy to understand. If you are going to use them, I'd advise you to check with your audience first to ensure they understand how to read them. In this video I will walk you through: 0:00 Intro 0:40 Data prep 1:17 Create the calculations 3:12 Build the view 4:08 How to get the first date at 12 o'clock 5:06 Build the trellis view (multiple starburst charts) 7:06 Adjust the size of the center 7:22 Labeling the center of the circle Get the workbook - https://www.vizwiz.com/2022/10/starbu...

RADIAL FIELD ABS([Sales]) // Change this to whichever measure you are using 2. ADJUSTER Float type parameter, default to 10, but need to adjust to get the correct date at the top 3. RADIAL ANGLE (INDEX()-[2. ADJUSTER]) * (1/WINDOW_COUNT(COUNT([1. RADIAL FIELD])))*2*PI() 4. RADIAL INNER Float type parameter, default to 1 5. RADIAL OUTER Float type parameter, default to 2 6. RADIAL LENGTH [4. RADIAL INNER]+ IIF(ATTR([Table Name])='Orders1',0, AVG([1. RADIAL FIELD])/WINDOW_MAX(AVG([1. RADIAL FIELD]))*([5. RADIAL OUTER]-[4.
