如果您想设置图表图例条目填充的文本为无色,以便它不会显示在图例中,请将LegendEntry.IsTextNoFill设置为true。
以下示例代码将图表的第二个图例条目填充的文本设置为无色。请下载这段代码中使用的sample excel file和由此生成的output excel file进行参考。
以下屏幕截图突出显示了此代码对sample excel file的影响。
#include <iostream>
#include "Aspose.Cells.h"
using namespace Aspose::Cells;
using namespace Aspose::Cells::Charts;
int main()
{
Aspose::Cells::Startup();
// Source directory path
U16String srcDir(u"..\\Data\\01_SourceDirectory\\");
// Output directory path
U16String outDir(u"..\\Data\\02_OutputDirectory\\");
// Path of input excel file
U16String inputFilePath = srcDir + u"Sample.xlsx";
// Path of output excel file
U16String outputFilePath = outDir + u"ChartLegendEntry_out.xlsx";
// Open the template file
Workbook workbook(inputFilePath);
// Access the first worksheet
Worksheet sheet = workbook.GetWorksheets().Get(0);
// Access the first chart inside the sheet
Chart chart = sheet.GetCharts().Get(0);
// Set text of second legend entry fill to none
chart.GetLegend().GetLegendEntries().Get(1).SetIsTextNoFill(true);
// Save the workbook in xlsx format
workbook.Save(outputFilePath, SaveFormat::Xlsx);
std::cout << "Chart legend entry modified successfully!" << std::endl;
Aspose::Cells::Cleanup();
