Adding a TextBlock (or label) on the end of a LineSeries DataPoint of a DataVisualizationChart

I'm creating a User Control componente of type DataVisualization.Chart. Right now, he accepts 4 range limits (1 range minimum of accept value and 1 maximum, also 1 range minimum of warning value and 1 maximum warning range value). So far, so good. It works. But i need to add a TextBlock (or label, or TextBox, whatever) at the end of the LineSeries.

This is my actual LineSeries:

Now i need to make something like this:

Even if the result is not the same, i need to put a label or textblock at the end of every LineDataPoint.

Any help will be appreciated.

Best Regards, Gustavo.
