	// Instantiating a Workbook object
	Workbook workbook = new Workbook();

	// Adding a new worksheet to the Workbook object
	int sheetIndex = workbook.Worksheets.Add();

	// Obtaining the reference of the newly added worksheet by passing its sheet index
	Worksheet worksheet = workbook.Worksheets[sheetIndex];

	// Adding sample values to cells
	worksheet.Cells["A1"].PutValue(50);
	worksheet.Cells["A2"].PutValue(100);
	worksheet.Cells["A3"].PutValue(150);
	worksheet.Cells["B1"].PutValue(60);
	worksheet.Cells["B2"].PutValue(32);
	worksheet.Cells["B3"].PutValue(50);

	// Adding a chart to the worksheet
	int chartIndex = worksheet.Charts.Add(Aspose.Cells.Charts.ChartType.Column, 5, 0, 15, 5);

	// Accessing the instance of the newly added chart
	Aspose.Cells.Charts.Chart chart = worksheet.Charts[chartIndex];

	// Adding SeriesCollection (chart data source) to the chart ranging from "A1" cell to "B3"
	chart.NSeries.Add("A1:B3", true);

	// Setting the title of a chart
	chart.Title.Text = "Title";

	// Setting the font color of the chart title to blue
	chart.Title.Font.Color = Color.Blue;

	// Move the legend to left
	chart.Legend.Position = LegendPositionType.Left;

	// Set font color of the legend
	chart.Legend.Font.Color = Color.Blue;



	// Save the file
	workbook.Save("chart_legend.xlsx");
