Description Markus Elfring 2018-12-13 09:48:07 UTC 
Trilean values can be displayed by the chart software already in principle.
But I imagine that ternary data can be configured and presented in more convenient ways for clearer diagrams of multiple time series.

* Variations exist for the representation of this data type.

  It would be nice to support it without adding transformations in extra columns (or rows).
  Can any known conversions become built-in for such input data?

* Intermediate increments should not be displayed as in comparison to regular line chart types.
  Specific lines or filled rectangles should be shown in lanes.

Sound reasonable...
