On Excel 2013 PC I'm trying to create an option to overlay the existing data in my graph with a another data series. For example I have 'Downloads' as my existing data series but I want to have slicers giving me the option to overlay the 'download' graph with another data series such as 'active users' and this has to be done at the click of a button.

Both Downloads and Active users are pivot table fields but I can only seem to get the slicers to display the range of data in each of those sections e.g. I can have slicers depending on the value of the downloads but not a slicer for the actual field e.g. 'downloads' itself.

If this is not possible then is this possible to code with VBA to have buttons on my graph to switch the layover data? If so, please elaborate!

Many thanks,
