Description

When WCartesianChart::setFollowCurve() is called, the curve can be hovered over with the mouse. It then displays data on the hovered over point.
This does not correctly work for all types of data, as it seems to always interpret is as a double.

See the screenshot:

The data in the x-axis is a date, and the label should display that data as a date.

Note: this comes from the widget gallery (https://www.webtoolkit.eu/widgets/graphics-charts/scatter-plot), where chart->setFollowCurve(2); is added to the last example.
