Grouped Barplot with Cut Y Axis in Two Directions (y and -y Axis) Introduction In this article, we will discuss how to create a grouped barplot with a cut y-axis in two directions: the positive y-axis and the negative y-axis. This type of plot is useful for visualizing the relationship between different categories and their corresponding values. We’ll go through the process step-by-step, explaining each technical term and providing examples to illustrate our points.

To apply this solution to your data, you can use SQL with PIVOT and GROUP BY. Here’s how you could do it: SELECT CustomerID, [1] AS Carrier1, [2] AS Service2, [3] AS Usage3 FROM YourTable PIVOT (COUNT(*) FOR CustomerID IN ([1], [2], [3])) AS PVT ORDER BY CustomerID; This query will create a table with the sum of counts for each CustomerID and its corresponding values in the pivot columns.
