Hi Domors.
Firstly, my DS is structured as follows:
Date: Type: Actual: Months Total Forecast:
2017/1 offline 1000 1200
2017/2 email 100 500
2017/2 refferal 500 500
.... and so on.
I have a series of Type defined which is added to the chart along with date and the sum of Actual.
Note, the Months Total Forecast is the forecast for the sum of all the types under the month, its not against each type.
The chart is as follows:

What I would like to do is add the Forecast as a Line Series, but simply its not working.
The problem is that 'Type' will not split out into its series.
At best, i receive various versions of this:

Is this due to the forecast (FC_MoM...) being a row item rather than stacked/unioned into the DS?
Any help appriciated.
Obviously what I hope to achieve is:

Rgds,
K.
