-----------------------------------------
This has been approved by the TC for inclusion (ages ago). So if it has not yet been included in the draft it should be!

> Key: OFFICE-3662
> URL: https://issues.oasis-open.org/browse/OFFICE-3662
> Project: OASIS Open Document Format for Office Applications (OpenDocument) TC
> Issue Type: Improvement
> Components: Chart
> Affects Versions: ODF 1.2 CD 07
> Reporter: Andreas Guelzow
> Assignee: Andreas Guelzow
> Priority: Major
> Fix For: ODF 1.3 CSD 01
>
>
> Currently ODF 1.2 has only 3 possible values for chart:interpolation. Since some ODF implementation have a much larger selection of interpolation types (e.g. closed splines, parabolic splines, cubic csplines, clamped csplines, various step type interpolations), we should add additional ones. I propose that initially we add some step-type interpolations.
> Step type interpolations are useful for various applications such as discrete survival curves as used in Kaplan-Meier analysis.
