title: How to have weekly and monthly data on Power BI dual axis chart?
body: <p>I have 2 time series of data, one that is a monthly value and one that is weekly. When I "expand" all down 1 level it kind of does what I want but it doesn't properly show the monthly values.</p>
  
  <p>Is there a way I can have a chart that shows the monthly values (and just months) for one set of data and weekly values for another set of data on the same chart?</p>
