Cum se formatează Numărul de etichete de date grafice

Folosind NumberFormat puteți specifica formatarea numerică a unei singure etichete de date a graficului.

Următorul exemplu de cod arată cum să formatați un număr de etichete de date:

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);

Cum să lucrați cu eticheta de date grafice

Folosind ChartDataLabel puteți specifica formatarea unei singure etichete de date a seriei de diagrame, cum ar fi Afișare / Ascundere LegendKey, CategoryName, SeriesName, valoare etc:

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);
