Description

CurveLabels in DateTimeSeries-Charts are not added.
reason imho is: ChartLabel wants WPointF as Parameter in creation which is class of double member's x and y. When rendering Labels in WCartesianChart.C (see Line 3414/renderCurveLabels) implicit mapToDeviceWithoutTransform is called with this double-typed Parameter for x too. But later in WAxis::mapToDevice and WAxis::getValue() x-Parameter has to be a cpp17::any of type WDateTime for AxisScale::DateTime. Otherwise mapping Returns nan for x.

Find attached your ChartsExample.c an h. I added two Event-Metods. ScatterPlotExample::OnMouseWentDown draws Label over clicked Position of ScatterPlot. TimeSeriesExample::OnMouseWentDown does not.
