How is the baseline measure being displayed? Is it a reference line?
the baseline is currently just another measure that I have added to each chart. Is there a way I could use that measure as a reference line and apply it to multiple charts simultaneously (through multiselect or something like that?). Also the measure is a time series, I would not want a constant value line
Hmm, it kind of depends on the view. You may try putting the baseline measure on the level of detail shelf. Then, add a reference line and choose that measure from the drop down menu.
it doesnt look like this will work because the Reference line dialog forces an aggregation (Sum, Avg) on the selected measure, which produces a flat line. I think I will just do this manually (dragging the baseline series to each chart)
