I have attached the closest I can come here.

oh and for anyone else attempting to help - this is a v10 workbook as that is what Nataraj supplied in the question.
I don't have time to do this, my suggestion would be to use a padded out data source for the target that has rows for all the months for each month and that way the running sum would have enough data to work.
If it is enough for a task to just get running totals on a view,
may be you would accept using Highlight action instead of Filter one.
The Bars on the target view are about to be changed
to something 'lighter' -- Dots or even Gantt bars (as in the attached).
The data don't need to be re-shaped.
Hope it could help.
