Can you please explain "tri-plotting"?

Sorry for being too vague in the description. A tri-plot is a barycentric plot based on 3 variables. Commonly refered to as a tri-plot or de Finetti diagram.

It is not currently possible to create a tenary-type chart (a.k.a. " ternary graph, triangle plot, simplex plot, or de Finetti diagram [being] a barycentric plot on three variables", Wikipedia) in Calc. In order for Calc to support this type of chart the ODF specification will need to be amended.

The <chart:chart> element has a chart:class attribute which specifies the type of chart and is detailed in ODF v1.2, Part 1, 19.15. Currently this attribute supports the values chart:area, chart:bar, chart:bubble, chart:circle, chart:filled-radar, chart:gantt, chart:line, chart:radar, chart:ring, chart:scatter, chart:stock, and chart:surface. A new chart:ternary or similar value for this attribute would need to be specified. The <chart:axis> element has a chart:dimension attribute that supports x, y, and z axes, which would seem sufficient for plotting a chart with three variables.

There is currently no open enhancement request that I can find for "tri", "ternary", or "Finetti" that relates to charts. Please file an enhancement bug and provide as much information about this new feature as possible. Include a link to this thread if required. Don't forget to mark your bug as an 'enhancement'. The QA team will be happy to help you triage your feature request in the bugtracker.

Please post a link to any bugs you file in a comment below using the format "fdo#123456".

Thanks!
