Would you be able to provide application, Because, You have choose the Fast Change rules. I recommend to create Combo chart with the Bar Measure (Check the Data points) and Line measure (Un check the Data points - If checked)
- Hope this could help
I am bit confused you are using Allowed Types - I think those values are not over riding. Might be you took Different way
Before develop something, think If placed (The Right information | To the right people | At the Right time | In the Right place | With the Right context)
Change the chart type to Combo Chart. In Presentation you can change settings to "Plot Value Inside the segments" so that Bar data points will be in between bar and it is clear to view both the data points.
