设置图表图例

使用 Aspose.Cells 管理图表的图例很简单传奇.

以下代码片段演示了如何管理图例：

            // 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");
