One of the more useful features of Power BI is the ability to set the sort order of a column based on another column's values.
A good example of this is if you have a bar chart showing a list of categories e.g. the work types. On the visual you have the option to sort ascending or descending but it my not be correct to display these in alphabetical order.
In this video I'll talk you through the steps of setting up a custom sort that allows you to define the sort order. This will allow you to display the list of categories in any order the choose. For example if you a list of work order status codes you might want to display them in the order that a work order would progress through the work management process flow
