Hi

I'm having an issue since I updated to 18.2 (was priori to 17.2)

I create Y axes in code behind :

  yAxis = new NumericYAxis();
                yAxis.Title = IdYAxis;

                yAxis.Tag = IdYAxis;

                AxisLabelSettings setaxlab = new AxisLabelSettings();
                switch (PositionYaxis)
                {
                    case ePositionYAxis.IN_LEFT: setaxlab.Location = AxisLabelsLocation.InsideLeft; break;
                    case ePositionYAxis.OUT_LEFT: setaxlab.Location = AxisLabelsLocation.OutsideLeft; break;
                    case ePositionYAxis.IN_RIGHT: setaxlab.Location = AxisLabelsLocation.InsideRight; break;
                    case ePositionYAxis.OUT_RIGHT: setaxlab.Location = AxisLabelsLocation.OutsideRight; break;
                }
                setaxlab.Foreground = new SolidColorBrush((Color)ColorConverter.ConvertFromString(couleurAxis));

                yAxis.LabelSettings = setaxlab;
                
                yAxis.Foreground = new SolidColorBrush((Color)ColorConverter.ConvertFromString(couleurAxis));


     

               TitleSettings titleset =(TitleSettings) YNumericAxisbase.TitleSettings.Clone();
                titleset.Foreground = new SolidColorBrush((Color)ColorConverter.ConvertFromString(couleurAxis));
                titleset.Angle = 270;


                yAxis.TitleSettings = titleset;



                yAxis.MajorStrokeDashArray = new DoubleCollection(new double[] { 1, 7 });
                yAxis.MajorStroke = new SolidColorBrush((Color)ColorConverter.ConvertFromString(couleurAxis));

                yAxis.MinimumValue = Miny;
                yAxis.MaximumValue = MaxY;


     
                _owner.Axes.Add(yAxis);

But I now have multiple Binding errors  when I run the software :

Those errors are repeated for each Y axe I add in the xamdatachart, I think it has to do with the axis title textblock.

For a reason I don't inderstand the textblock semmes to try to find its values directly on the control Viewmodel ...  I did not have those errors unsing 17.2.

If I create the axes in xaml , I dont have any errors, I tried to compare the objects (xaml created axis vs code created axis) but could not find the cause of this problem.

Thanks in advance
