A diagram report allows you to define a process flow through connecting different measures.
When you first create a diagram, it'll prompt you to choose a field defining the end condition for steps. For example, we'll choose Deal Status to help define that condition:
Choosing that initial field creates two filters, one for the 'in process' part of the pipeline and one for the 'end' part of the pipeline. We'll edit the 'end' filter and choose Won and Lost, to define those two cases as the end:
Next, we'll choose the fields going into the diagram. For this example, we'll use Current Stage and Deal Size, since we want to show deal value per stage in the diagram:
You can add additional measures to the diagram as well. For example, we can add Opportunity Count:
You can also set up conditional formatting on your diagram. For example, in order to show any node with more than $50,000 in sales in green, we could put in the following conditional formatting:
Which gives us the following result:
