DataviewMappings Table with two measures

[Anonymous]

Dear PBI custom viz developer community,

I have a set of data in the from of

X Values	Y1 Values	Y2 Values	Overwritten
1	50	50	1
2	45	42	0
2	47	42	0
3	33	34	1
3	31	34	0
3	30	34	0
4	21	26	0
4	10	26	1

I need to create a datamapping to be able to visualise the data

X values are my categorical data,

Y1 values should not be summarised and I am using them to display as a scatterplot,

Y2 values are my summarised data as averages of Y2 at each X1 which I am displaying as a line

Overwritten will be used as my legend, (if the value is 1 show as different colour) 

I would need your help to understand what would be the best dataviewmapping for developing a custom visuals given the above data

Appreciate your help 

D3.JS CustomVisual - Are interactions possible? 

DataViewMappings with both table and categorical.
