用C++实现Z轴

可能的使用场景
对于一些具有深度(系列)轴的3D图表,例如3D柱状图、3D圆锥体图或3D金字塔图,也称为Z轴,您可以进行更改。您可以指定刻度标记之间的间隔、轴标签和其他操作。
处理主轴和第二轴,就像处理Microsoft Excel一样
请查看以下示例代码,它创建一个新的Excel文件,并将图表的值放在第一个工作表中。然后我们添加一个图表,将图表类型设置为柱状3D,然后可以看到深度轴也称为Z轴。
示例代码
#include <iostream>
#include "Aspose.Cells.h"
using namespace Aspose::Cells;
using namespace Aspose::Cells::Charts;
int main()
{
Aspose::Cells::Startup();
// Create an instance of Workbook
Workbook workbook;
// Get the first worksheet
Worksheet worksheet = workbook.GetWorksheets().Get(0);
// Put values to cells for creating chart
worksheet.GetCells().Get(u"A1").PutValue(u"A");
worksheet.GetCells().Get(u"B1").PutValue(u"B");
worksheet.GetCells().Get(u"C1").PutValue(u"C");
worksheet.GetCells().Get(u"A2").PutValue(2);
worksheet.GetCells().Get(u"A3").PutValue(1);
worksheet.GetCells().Get(u"B2").PutValue(2);
worksheet.GetCells().Get(u"B3").PutValue(3);
worksheet.GetCells().Get(u"C2").PutValue(2);
worksheet.GetCells().Get(u"C3").PutValue(3);
// Add a chart to the worksheet
int chartIndex = worksheet.GetCharts().Add(ChartType::Column3D, 9, 6, 25, 16);
// Access the instance of the newly added chart
Chart chart = worksheet.GetCharts().Get(chartIndex);
// Calculate the chart
chart.Calculate();
// Add SeriesCollection (chart data source) to the chart ranging from "A2" cell to "C3"
chart.SetChartDataRange(u"A2:C3", true);
// Hide the CategoryAxis axis
chart.GetCategoryAxis().SetIsVisible(false);
// Hide the ValueAxis axis
chart.GetValueAxis().SetIsVisible(false);
// Save the file
workbook.Save(u"ZAxis.xlsx");
Aspose::Cells::Cleanup();
return 0;
