I'm not sure I understand what you try to achieve. But let's start with what you want to show, and leave where you want to show it until later.
You obviously have two different months in your data model: Collection_Month and Setup_Month. Further, a record can be associated with one Collection_Month and another Setup_Month (this is visible in the chart). And now you do not want to include records that have different months in these two fields?
Exactly my data model has 2 dates. The snapshot above is basically what i want, and its kind of perfect, but for the ease of readability of data i want all the setup amount in one column. It should split by Setup and collection date.
Condition- I only need those records where my collection and setup dates are same.
