Add an average line from the "add more analysis to your visual" menu is now displaying the average c

I am working on a column of lines that represents the stages of a project on the x-axis and the average time it takes to go from one stage to another but the problem is that when I add the workers field to the legends field it does not allow me to add another I see the average field to a secondary line so I decided to add a further analysis to my visual but when I select the average line it gives me a straight line but it doesn't work that way
On the right is the line as it should look and on the left is what it looks like.

When you add an average line it will give the global average only. You can may be try bar and line chart to add an average line @RobertoMonzon
