用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。

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

#include <iostream>
#include "Aspose.Cells.h"
using namespace Aspose::Cells;

int main()
{
    Aspose::Cells::Startup();

    // Create an instance of Workbook
    Workbook workbook(u"Volume-Open-High-Low-Close.xlsx");

    // Access the first worksheet
    Worksheet worksheet = workbook.GetWorksheets().Get(0);

    // Create High-Low-Close-Stock Chart
    int32_t pieIdx = worksheet.GetCharts().Add(ChartType::StockVolumeOpenHighLowClose, 5, 6, 20, 12);

    // Retrieve the Chart object
    Chart chart = worksheet.GetCharts().Get(pieIdx);

    // Set the legend to be shown
    chart.SetShowLegend(true);

    // Set the chart title name 
    chart.GetTitle().SetText(u"Volume-Open-High-Low-Close Stock");

    // Set the Legend at the bottom of the chart area
    chart.GetLegend().SetPosition(LegendPositionType::Bottom);

    // Set data range
    chart.SetChartDataRange(u"A1:F9", true);

    // Set category data 
    chart.GetNSeries().GetCategoryData() = u"A2:A9";

    // Set Color for the first series (Volume) data 
    chart.GetNSeries().Get(0).GetArea().SetForegroundColor(Color{0xff, 79, 129, 189});

    // Fill the PlotArea area with nothing 
    chart.GetPlotArea().GetArea().GetFillFormat().SetFillType(FillType::None);

    // Save the Excel file
    workbook.Save(u"out.xlsx");

    std::cout << "Chart created and file saved successfully!" << std::endl;

    Aspose::Cells::Cleanup();
}
