以下示例代码解释了如何使用Aspose.Cells将图表转换为SVG格式图像。该代码加载源Microsoft Excel文件,然后将第一个工作表上找到的第一个图表保存为SVG。

const path = require("path");
const AsposeCells = require("aspose.cells.node");

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");

// Create workbook object from source file
const workbook = new AsposeCells.Workbook(path.join(dataDir, "SampleChartBook.xlsx"));

// Access first worksheet
const worksheet = workbook.getWorksheets().get(0);

// Access first chart inside the worksheet
const chart = worksheet.getCharts().get(0);

// Set image or print options
const opts = new AsposeCells.ImageOrPrintOptions();
opts.setImageType(AsposeCells.ImageType.Svg);

// Save the chart to svg format
chart.toImage(path.join(dataDir, "Image_out.svg"), opts);
