I am trying to compare the average attendance in the league to a single team average attendance for combined years.
I have confused on what is the shared axis assuming years. Then how to get the double Y axis to calculate.
I have to choose the most appropriate visualization to show how the team's (Chicago White Sox) attendance average combined for all years '06-'14) compares with the attendance average of all other teams in the League.
I assume the League average attendance would exclude the WS.
I started with two separate visualizations, but I am convince that the line and stacked column chart should do the trick.
I am thinking the years at the bottom (x-axis) average attendance on Y- axis. Thes would be stacked column and the WS average attendance would show a line going across the years.
Hopefully this sample data is enough to work with. Thanks,
How do I send you the sample data?
Since you have placed "years" on X-axis, "average attendance" on Y-axis, to show a line which represents the average value of WS attendance across the whole year, maybe you need a measure similar to below, and add it to "lines" section of the chart.
WS average attendance = CALCULATE ( AVERAGE ( Table[WS attendance] ), ALL ( Table[years] ) )
For more advice, please follow this blog to provide more detailed sample data and desired output.
