Hidden series do not get updated when set visible again

[V0du]

Steps to reproduce:

1. Hide any series by clicking on the legend's items
2. Update the data (my series are bound to a List of custom items and I use the serie's Mapping delegate to convert the item to DataPoints)
3. Refresh the plot (I bind to the plot's InvalidateFlag property and increment its value)
4. Make the series visible again by clicking on the legend's items

The series that were invisible when the data changed are not updated on the plot.

Can you clarify, is this an issue with the contrib provision (e.g. when defining series in XAML) or with the normal PlotModel?

[V0du]

This is in the contrib; I'm using the Plot class and defining legends and series in XAML.

Update:
It seems this only happens when using the Mapping delegate on the series to convert a custom class to DataPoint.
it works fine if I bind the serie's ItemsSource to a collection of DataPoints.

That makes sense: if the source is already DataPoints then it skips the update anyway. Sorry I've not had time to look into this yet.
