    It seems, there is a problem when using CartesianPlotBandAnnotation with specified Fill property.
    In such situation, the annotations cover all chart area, including Series.

    When I try to define some tranparency (alfa-value for color) - series are plotted, but they look like behind the fog.
    Also Chart grid lines are visible behind the annotations. 
    In previous version of charting (RadChart) - it worked much better.

    Example screen shots are as attachments. The data is plotted just above the horizontal axis - so that it's hardly visible on the chartView_annotations example.

    Best regards

    Hi Marcin,

    The reason for the series not being visible is that the annotations are added to the same Canvas that the series are added to and the annotations have a greater ZIndex. This is by design. You can change the ZIndex property of the annotations (not the Canvas.ZIndex, but the annotation.ZIndex) in order to have the annotation beneath the series. You can try values in the range of -250 and -300 and see how it goes.

    Thank You!
    -200 seems to perfect value ;)
