When true, X values in the data set are relative to the current pointStart, pointInterval and pointIntervalUnit settings. This allows compression of the data for datasets with irregular X values.

The real X values are computed on the formula f(x) = ax + b, where a is the pointInterval (optionally with a time unit given by pointIntervalUnit), and b is the pointStart.
