 * - Next, series.data contains those values converted to points, but in case the series data length
 * exceeds the cropThreshold, or if the data is grouped, series.data doesn't contain all the points. It
 * only contains the points that have been created on demand.
 * - Then there's series.points that contains all currently visible point objects. In case of cropping,
 * the cropped-away points are not part of this array. The series.points array starts at series.cropStart
 * compared to series.data and series.options.data. If however the series data is grouped, these can't
 * be correlated one to one.
 * - series.xData and series.processedXData contain clean x values, equivalent to series.data and series.points.
