        <pre>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.
  <a href="https://en.wikipedia.org/wiki/Three-valued_logic#Representation_of_values">https://en.wikipedia.org/wiki/Three-valued_logic#Representation_of_values</a>

  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.
