Annotations rendered below axis

[Viollier]

Hello. I am using a RadCartesianChartView with CartesianGridLineAnnotations set on the Y axis. When zooming and panning the chart, the annotations get rendered below the X axis, both the labels and the strokes. I've attached 2 screenshots to demonstrate the effect. Is there a property that we can change to prevent the annotations from going below the X axis? 

 

Thank you.

Hello,

Thanks for writing and for the attached screenshots.

Would it be possible if you attached the source of your project or just a snippet that we can use to exactly reproduce the scenario and see what goes wrong?

If you want to attach files, please open a new support ticket and do it there.

Thanks for your time!

Hi Deyan,

i will try to post relevant snippets here. We are using custom annotations that are added as you see below:

 

void AddValueAnnotations()
{
    var labels = ChartModel.Labels;
    foreach (KeyValuePair<double, ValueType> entry in labels)
    {
        AddAnnotation(entry.Key, false);
    }
}

void AddAnnotation(double value, bool showLine)
{
    CartesianGridLineAnnotation annotation = new CartesianGridLineAnnotation(Chart.VerticalAxis, value);
    annotation.ClipToPlotArea = false;
    if (showLine)
    {
        annotation.StrokeColor = Color.Argb(204, 153, 217, 194);
    }
    else
    {
        annotation.StrokeColor = Color.Argb(0, 0, 0, 0);
    }
    annotation.StrokeWidth = 1;
    annotation.Label = string.Format("{0:0.00}", value);
    annotation.LabelLocation = ChartAnnotationLabelLocation.Left;
    annotation.LabelHorizontalOffset = -7;
    annotation.LabelVerticalOffset = -10;
    Chart.Annotations.Add(annotation);
}

Hi,

Thanks for writing.

I see that you are setting the ClipToPlotArea property to false. This might be causing the behavior you want to avoid. Can you try setting the property to true or there is a specific reason for it being set to false?
