This chart is a histogram that displays preparation time in minutes on the X-axis and the count of orders with that preparation time.
Initially, I used the histogram visual, but I found it limiting. I wanted to display the count of orders on each bar and/or the percentage of the total that each bar represents.
So, I switched to a bar chart, where I have the Order Preparation Time field on the X-axis and the distinct count of the OrderKey field as the value/measure.
