用Node.js通过C++创建成交量 开盘 最高 最低 收盘（VOHLC）股票图表

可能的使用场景

我们要看的第四个股票图表是成交量开盘最高最低收盘图表。同样，数据顺序必须正确。若需重新整理数据，应在设置图表前完成。该图表包括在第一（类别）列后立即的一列成交量，图表上有一个主轴显示成交量，价格移动到副轴。

成交量-开盘-最高-最低-收盘（VHLC）股票图表

示例代码

以下示例代码加载了示例Excel文件，并生成了输出Excel文件。

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

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
const filePath = path.join(dataDir, "Volume-Open-High-Low-Close.xlsx");

// Create an instance of Workbook
const workbook = new AsposeCells.Workbook(filePath);
// Access the first worksheet.
const worksheet = workbook.getWorksheets().get(0);
// Create High-Low-Close-Stock Chart
const pieIdx = worksheet.getCharts().add(AsposeCells.ChartType.StockVolumeOpenHighLowClose, 5, 6, 20, 12);
// Retrieve the Chart object
const chart = worksheet.getCharts().get(pieIdx);
// Set the legend can be showed
chart.setShowLegend(true);
// Set the chart title name 
chart.getTitle().setText("Volume-Open-High-Low-Close Stock");
// Set the Legend at the bottom of the chart area
chart.getLegend().setPosition(AsposeCells.LegendPositionType.Bottom);
// Set data range
chart.setChartDataRange("A1:F9", true);
// Set category data 
chart.getNSeries().setCategoryData("A2:A9");
// Set Color for the first series (Volume) data 
chart.getNSeries().get(0).getArea().setForegroundColor(new AsposeCells.Color(79, 129, 189));
// Fill the PlotArea area with nothing 
chart.getPlotArea().getArea().getFillFormat().setFillType(AsposeCells.FillType.None);
// Save the Excel file
workbook.save("out.xlsx");
