SSRS Report Series with Null value

yes,it was one the bad days when you get stuck with unknown devil (so called bug where you don't have any idea whats happening)..

in SSRS dundas chart,today I was publishing a chart where a series (months of year) has value in some places but not in all.but series was visible for all the x - axis data ...after juggling alot I found a solution..you can see the solution here

In short ..series have a property of empty points ..just make changes over there
