Reports - plotting a straight line

0
Dawn Borg Costanzi (26●5●4) | asked Jul 11 '08, 6:30 a.m.
Hi,

I would like to plot a diagonal straight line, superimposed on the Burndown chart. At the point where x=0, ie at the begninning of an iteration, the y value would be the sum of estimes of all workitems in this iteration, whereas the y value would be 0 at end date of the iteration.

Does anyone have any idea how to do this please?

Thanks

I think the easiest way to do this would be to use javascript in the
Chart's various methods to synthesize a second series, with the two data
points that you propose. The end date of the iteration should be
available from the Common Data Set (we may even store it in a global
javascript variable called endDate), and the first data point would be
the same as the first data point in the other (burndown) series.

This, of course, would involve using the BIRT designer to modify the
report template (.rptdesign file) and then deploying the new template to
your server.

The technique I'm describing above isn't trivial, and I don't have any
sample code that demonstrates synthesizing of a new series and data
points, sorry.

Hope this helps.

But since this is a very standard component of a burndown chart, is there an enhancement request or should we make one to either add this to the current report or add a second report that includes it?

It also isn't quite as trivial as one might think since we need to account for non-work days that are included in the graph (e.g., the weekend between sprint end points).

Certainly, feel free to open an enhancement request and we'll
investigate adding this functionality to the existing report (or, as you
say, make a second report - actually, we could just add a boolean report
parameter that would determine whether the new line is vsible).
