Werk met Grafiek Data Etiket

Aspose.Words laat gebruikers toe om op verskillende maniere met ChartDataLabel te werk.

Hoe Om Die Aantal Grafiekdata-Etikette Te Formateer

Met behulp van NumberFormat kan jy nommer formatering van’n enkele data etiket van die grafiek spesifiseer.

Die volgende kode voorbeeld toon hoe om’n nommer van die data etiket te formateer:

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);

Hoe Om Te Werk Met Chart Data Label

Gebruik ChartDataLabel jy in staat is om die formatering van’n enkele data etiket van die grafiek reeks spesifiseer, soos wys / verberg LegendKey, CategoryName, SeriesName, waarde ens:

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);
