Trying to overlay meta data onto a chart

[gsbeaton]

Hi Folks,

I have a chart that I want to overlay meta data onto to show key information, such as when employees joined and left our team, which may help to explain the data more.

At the moment I have an inline table, holding the meta data joined on MonthYear to the main table and I am trying to show the data as an additional dimension.  It's not working too well, does anyone have any ideas as to how I could go about achieving this?  The chart below shows what I am trying to achieve.

Many thanks

George
