When the coordinate has only one value (' December 2012 ', 0), neither horizontal nor vertical coordinate has any value displayed. I want to set some default values at this time, such as (0, 1, 2, 3, 4, 5). How to set it? thank you

Reproduce the single-value coordinate case with Flutter 3.3.0-0.5.pre and fl_chart 0.55.1, using the supplied screenshot and issue description as the expected scenario. Read the chart coordinate and axis-label configuration exposed by the library, then verify that default horizontal and vertical values appear without breaking multi-value charts.
