Time intelligent slicer to change X-axis dependent on whether quarterly or monthly reported

[daniellamoore29]

I have a stacked bar and line chart which has Qtr and Month along the x-axis. 

I have to use a drill-down to show the qtr or month otherwise it shows blanks.

I want to show EITHER month or qtr when the metric name is selected from the drop-down. 

I have a column which defines whether this is a qtr or monthly report, so I assume I can create a measure but I have no idea how.
