{
    this.Text = "How to Create Chart WinForm .NET 8";

    // Clear ChartAreas, Series
    chart1.ChartAreas.Clear();
    chart1.Series.Clear();

    // Create Chart Area
    ChartArea chartArea = new ChartArea("GraphArea");
    chartArea.AxisX.Title = "Months";
    chartArea.AxisY.Title = "Rs. In Lakhs";

    // Add Chart Area
    chart1.ChartAreas.Add(chartArea);

    // Create a Series and set type to Bar
    Series series = new Series("Sales")
    {
        ChartType = SeriesChartType.Bar,
        IsValueShownAsLabel = true
    };

    // Add Data Points
    series.Points.AddXY(1, 150);
    series.Points.AddXY(2, 70);
    series.Points.AddXY(3, 90);
    series.Points.AddXY(4, 150);
    series.Points.AddXY(5, 170);
    series.Points.AddXY(6, 90);
    series.Points.AddXY(7, 130);
    series.Points.AddXY(8, 70);
    series.Points.AddXY(9, 190);
    series.Points.AddXY(10, 120);
    series.Points.AddXY(11, 90);
    series.Points.AddXY(12, 70);

    // Add Series to Chart
    chart1.Series.Add(series);

    // Set Fonts
    series.Font = new Font("Verdana", 11);
    chart1.ChartAreas[0].AxisY.LabelStyle.Font = new Font("Segoe UI", 9);
}

To change the Chart Type, set the following property.

// Create a Series and set type to Bar
Series series = new Series("Sales")
{
    ChartType = SeriesChartType.Line,
    IsValueShownAsLabel = true
};
