Chart.js: Chart v3.0.0-rc.5 - Object [] using custom properties sort order x-axis error

Expected Behavior

Why is the order of the X-axis not as it was defined in the options?

Since I do not always have a value for the defined time span (x-axis) for all series, I would like to use an “Object [] using custom properties” as the data source.

Unfortunately that doesn’t work or I don’t know how to set this up so that the order of the X-axis values is displayed correctly.

Current Behavior

Possible Solution
