          <chart:ChartLegend/>

        </chart:SfChart.Legend>

        <chart:SfChart.Title>

          <chart:ChartTitle Text="Student Score"/>

        </chart:SfChart.Title>

        <chart:SfChart.PrimaryAxis>

          <chart:CategoryAxis>

            <chart:CategoryAxis.Title>

              <chart:ChartAxisTitle Text="Name"/>

            </chart:CategoryAxis.Title>

          </chart:CategoryAxis>

        </chart:SfChart.PrimaryAxis>

        <chart:SfChart.SecondaryAxis>

          <chart:NumericalAxis>

            <chart:NumericalAxis.Title>

              <chart:ChartAxisTitle Text="Score"/>

            </chart:NumericalAxis.Title>

          </chart:NumericalAxis>

        </chart:SfChart.SecondaryAxis>
