After 19 days of Data School, I had a quiz today to check my level of learning in Tableau. Among the tasks were some charts I had never built before. Among them was a Circle Timeline. Since I really liked the chart, here are the instructions (Sample Superstore).
What is a Circle Timeline?
A circle timeline or bubble timeline is a way to display a series of dates on a timeline with a measure used to size the circles and, optionally, another measure to color the circles. A circle timeline combines a time series, a dot plot, and packed bubbles into the same view.
1.Right Click and Drag “Order Date” to the Columns and going to choose continue with month.
