Aggregation in Front end chart

[Georgy_Paul]

Hi. So I have a data with attributes, for example 

Attribute	Value
A	4
B	5
C	6
D	7
E	8
F	9

I need to show a line chart with the values for each of these attribute and then A+B as G as well.

So basically in line chart I should be having all the attributes along with G = 9.

I can't do this in backend. Is there anyway to do this in expression in line chart.
