Hi Vamsi,
Thank you for using Syncfusion product.
We can plot the graph with student names on X axes by creating Labels for the ChartPoints. We can display the mark range on Y axes by setting Range values. Kindly review the code snippet.
// Displaying names in X axes
this.chartControl1.PrimaryXAxis.TickLabelsDrawingMode = ChartAxisTickLabelDrawingMode.UserMode;
this.chartControl1.PrimaryXAxis.Labels.Clear();
this.chartControl1.PrimaryXAxis.Labels.Add(new ChartAxisLabel("Christ", Color.Crimson, new Font("Times New Roman", 13), 0, "", ChartValueType.Custom));
this.chartControl1.PrimaryXAxis.Labels.Add(new ChartAxisLabel("Andrey", Color.Crimson, new Font("Times New Roman", 13), 1, "", ChartValueType.Custom));
this.chartControl1.PrimaryXAxis.Labels.Add(new ChartAxisLabel("James", Color.Crimson, new Font("Times New Roman", 13), 2, "", ChartValueType.Custom));
this.chartControl1.PrimaryYAxis.RangePaddingType = ChartAxisRangePaddingType.None;
this.chartControl1.PrimaryYAxis.Range.Interval = 10;
this.chartControl1.PrimaryYAxis.Range.Min = 10;
this.chartControl1.PrimaryYAxis.Range.Max = 100;
Please take a look at the sample and let me know if its helpful.
