got a line chart in which I'm counting the defects that are detected either post or pre release date (with full accumulation)
but to those that are pre-release I'm adding to them the accumulated value of the post release defects
check attached document
I have two wiered behaviors (ignore point 1)
1.the numbers are affected by the selection of the severity though the severity values are set in set analysis of the expression
2. the total should be 479 at month 11 however chart 1 is showing 473 whereas if to the post-release-defects I add the pre-release-defects I get on chart 2 479
