Problem with "Assigned independent axis cannot be used. This may be due to an unset Orientation property for the axis." in wpf chart c#

I want implement rotation and interval of axis label on x axis with LinearAxis in code behind.

lineSeria = new LineSeries();
                linAxis = new LinearAxis();
                linAxis.Orientation = AxisOrientation.X;
                linAxis.Location = AxisLocation.Bottom;
                linAxis.Interval = 10;
                

                var xLabel = new Style(typeof(AxisLabel));
                var rotation = new Setter(AxisLabel.RenderTransformProperty, new RotateTransform() { Angle = -90, CenterX = 50, CenterY = 1 });
                xLabel.Setters.Add(rotation);
                linAxis.AxisLabelStyle = xLabel;
                
                
                lineSeria.ItemsSource = drowMap[zoomedPointElem.Key];
                lineSeria.DependentValuePath = "Value";
                lineSeria.IndependentValuePath = "Key";
                lineSeria.IndependentAxis = linAxis;


                chart[coefficient].Series.Add(lineSeria);

 I did this way but something i missed, got this problem  "Assigned independent axis cannot be used. This may be due to an unset Orientation property for the axis." How can i fix it, need code behind please. Thank you
