Multiple Dimention in combo chart?

[#1]

Dear Friends

I have created a combo chart which is adding cumulative savings based on project end date.

The chart look like:

For every qtr I have added the target reference line on y axis.

However, I need to add the Quater target as a line graph instead of reference line.

Q1 = Q1 Target

Q2 = Q1 + Q2 Target

Q3 = Q1+ Q2+ Q3 Target

Q4=  Q1+ Q2+ Q3 + Q4 Target

How to add another dimension where I can plot line graph based on specific date?

Please share some examples.

Thanks!

Rahul

Please post an example document with sample data and an example of what the result chart should look like.
