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。
#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();
