Bekerja dengan Label Data Bagan

Aspose.Words memungkinkan pengguna untuk bekerja dengan ChartDataLabel dengan berbagai cara.

Cara Memformat Jumlah Label Data Bagan

Menggunakan NumberFormat Anda dapat menentukan pemformatan angka dari satu label data bagan.

Contoh kode berikut menunjukkan cara memformat sejumlah label data:

For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-C
System::SharedPtr<Document> doc = System::MakeObject<Document>();
System::SharedPtr<DocumentBuilder> builder = System::MakeObject<DocumentBuilder>(doc);

// Add chart with default data.
System::SharedPtr<Shape> shape = builder->InsertChart(ChartType::Line, 432, 252);
System::SharedPtr<Chart> chart = shape->get_Chart();
chart->get_Title()->set_Text(u"Data Labels With Different Number Format");

// Delete default generated series.
chart->get_Series()->Clear();

// Add new series
System::SharedPtr<ChartSeries> series1 = chart->get_Series()->Add(u"AW Series 1", System::MakeArray<System::String>({u"AW0", u"AW1", u"AW2"}), System::MakeArray<double>({2.5, 1.5, 3.5}));

series1->set_HasDataLabels(true);
series1->get_DataLabels()->set_ShowValue(true);
series1->get_DataLabels()->idx_get(0)->get_NumberFormat()->set_FormatCode(u"\"$\"#,##0.00");
series1->get_DataLabels()->idx_get(1)->get_NumberFormat()->set_FormatCode(u"dd/mm/yyyy");
series1->get_DataLabels()->idx_get(2)->get_NumberFormat()->set_FormatCode(u"0.00%");

// Or you can set format code to be linked to a source cell,
// in this case NumberFormat will be reset to general and inherited from a source cell.
series1->get_DataLabels()->idx_get(2)->get_NumberFormat()->set_IsLinkedToSource(true);

System::String outputPath = outputDataDir + u"ChartNumberFormat.docx";
doc->Save(outputPath);

Cara Bekerja Dengan Label Data Bagan

Menggunakan ChartDataLabel Anda dapat menentukan pemformatan label data tunggal dari rangkaian bagan, seperti tampilkan / sembunyikan LegendKey, CategoryName, SeriesName, Nilai dll:

For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-C
System::SharedPtr<Document> doc = System::MakeObject<Document>();
System::SharedPtr<DocumentBuilder> builder = System::MakeObject<DocumentBuilder>(doc);

System::SharedPtr<Shape> shape = builder->InsertChart(ChartType::Bar, 432, 252);
System::SharedPtr<Chart> chart = shape->get_Chart();

// Get first series.
System::SharedPtr<ChartSeries> series0 = shape->get_Chart()->get_Series()->idx_get(0);

System::SharedPtr<ChartDataLabelCollection> labels = series0->get_DataLabels();

// Set properties.
labels->set_ShowLegendKey(true);

// By default, when you add data labels to the data points in a pie chart, leader lines are displayed for data labels that are
// Positioned far outside the end of data points. Leader lines create a visual connection between a data label and its
// Corresponding data point.
labels->set_ShowLeaderLines(true);

labels->set_ShowCategoryName(false);
labels->set_ShowPercentage(false);
labels->set_ShowSeriesName(true);
labels->set_ShowValue(true);
labels->set_Separator(u"/");
labels->set_ShowValue(true);

System::String outputPath = outputDataDir + u"SimpleBarChart_out.docx";
doc->Save(outputPath);
