Highlighting no longer works

Tested change from 4.0.0 to 4.0.2.

partitioningIndex appears to be used incorrectly. $0.x == xValue should be a different closure that runs $0.x >= xValue. Existing match closure should be used for .prefix(while:) only.

The fix:

open override func entriesForXValue(_ xValue: Double) -> [ChartDataEntry]
{
    let belongsInSecondPartition: (ChartDataEntry) -> Bool = { $0.x >= xValue }
    let i = partitioningIndex(where: belongsInSecondPartition)
    guard i < endIndex else { return [] }

    let match: (ChartDataEntry) -> Bool = { $0.x == xValue }
    return self[i...].prefix(while: match)
}

Think I have a proper fix open for this #4817 which is basically the same as yours with a few extra lines to handle closest values in a more elegant way
