Hi guys , it doesn't work when i apply customized style to Axis PrimaryY on XamWebChart , neither in xaml nor in the code behind .

in code :

 Axis aY = _dataChart.Axes.FirstOrDefault<Axis>(axis => axis.AxisType == AxisType.PrimaryY);
            if (aY == null)
            {
                aY = new Axis { AxisType = AxisType.PrimaryY };
                //it works when properties are set in this way
              /*  aY.AutoRange = false;
                aY.Minimum = - 70;
                aY.Maximum = 100;
                aY.Unit = 10;*/

                //it doesn't work when apply style to aY
                aY.Style = (Style)this.Resources["AxisStyle1"];

                _dataChart.Axes.Add(aY);
            }

in Xaml:
