            chartControl1.DataAdapter = adapter;

            // Specify data members to bind the chart's series template.

            chartControl1.SeriesTemplate.View = new StackedBarSeriesView();

            // Adjust the X-axis and series labels' appearance.
            chartControl1.SeriesTemplate.LabelsVisibility = DefaultBoolean.False;

            // Dock the chart into its parent, and add it to the current form.
            chartControl1.Dock = DockStyle.Fill;
