So legen Sie die Eigenschaften der Diagrammachse fest

Wenn Sie mit Diagrammachse, Skalierung und Anzeigeeinheiten für die Wertachse arbeiten möchten, verwenden Sie bitte die Klassen ChartAxis, AxisDisplayUnit und AxisScaling.

Das folgende Codebeispiel zeigt, wie X- und Y-Achsen-Eigenschaften definiert werden:

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);

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

// Clear demo data.
chart->get_Series()->Clear();

// Fill data.
System::ArrayPtr<System::DateTime> dates = System::MakeArray<System::DateTime>({System::DateTime(2002, 1, 1),
                                                                                System::DateTime(2002, 6, 1),
                                                                                System::DateTime(2002, 7, 1),
                                                                                System::DateTime(2002, 8, 1),
                                                                                System::DateTime(2002, 9, 1)});
chart->get_Series()->Add(u"AW Series 1", dates, System::MakeArray<double>({640, 320, 280, 120, 150}));

System::SharedPtr<ChartAxis> xAxis = chart->get_AxisX();
System::SharedPtr<ChartAxis> yAxis = chart->get_AxisY();

// Change the X axis to be category instead of date, so all the points will be put with equal interval on the X axis.
xAxis->set_CategoryType(AxisCategoryType::Category);

// Define X axis properties.
xAxis->set_Crosses(AxisCrosses::Custom);
xAxis->set_CrossesAt(3);
// measured in display units of the Y axis (hundreds)
xAxis->set_ReverseOrder(true);
xAxis->set_MajorTickMark(AxisTickMark::Cross);
xAxis->set_MinorTickMark(AxisTickMark::Outside);
xAxis->set_TickLabelOffset(200);

// Define Y axis properties.
yAxis->set_TickLabelPosition(AxisTickLabelPosition::High);
yAxis->set_MajorUnit(100);
yAxis->set_MinorUnit(50);
yAxis->get_DisplayUnit()->set_Unit(AxisBuiltInUnit::Hundreds);
yAxis->get_Scaling()->set_Minimum(System::MakeObject<AxisBound>(100));
yAxis->get_Scaling()->set_Maximum(System::MakeObject<AxisBound>(700));

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

So stellen Sie den Datums- / Uhrzeitwert der Achse ein

Das folgende Codebeispiel zeigt, wie Datums-/ Uhrzeitwerte für Achseneigenschaften festgelegt werden:

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);

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

// Clear demo data.
chart->get_Series()->Clear();

// Fill data.
System::ArrayPtr<System::DateTime> dates = System::MakeArray<System::DateTime>({System::DateTime(2017, 11, 6),
                                                                                System::DateTime(2017, 11, 9),
                                                                                System::DateTime(2017, 11, 15),
                                                                                System::DateTime(2017, 11, 21),
                                                                                System::DateTime(2017, 11, 25),
                                                                                System::DateTime(2017, 11, 29)});
chart->get_Series()->Add(u"AW Series 1", dates, System::MakeArray<double>({1.2, 0.3, 2.1, 2.9, 4.2, 5.3}));

// Set X axis bounds.
System::SharedPtr<ChartAxis> xAxis = chart->get_AxisX();
xAxis->get_Scaling()->set_Minimum(System::MakeObject<AxisBound>((System::DateTime(2017, 11, 5)).ToOADate()));
xAxis->get_Scaling()->set_Maximum(System::MakeObject<AxisBound>((System::DateTime(2017, 12, 3)).ToOADate()));

// Set major units to a week and minor units to a day.
xAxis->set_MajorUnit(7);
xAxis->set_MinorUnit(1);
xAxis->set_MajorTickMark(AxisTickMark::Cross);
xAxis->set_MinorTickMark(AxisTickMark::Outside);

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

So formatieren Sie den Zahlenwert der Achse

Das folgende Codebeispiel zeigt, wie Sie das Format von Zahlen auf der Wertachse ändern:

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);

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

// Clear demo data.
chart->get_Series()->Clear();

// Fill data.
chart->get_Series()->Add(u"AW Series 1",
                         System::MakeArray<System::String>({u"Item 1", u"Item 2", u"Item 3", u"Item 4", u"Item 5"}),
                         System::MakeArray<double>({1900000, 850000, 2100000, 600000, 1500000}));

// Set number format.
chart->get_AxisY()->get_NumberFormat()->set_FormatCode(u"#,##0");

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

So legen Sie die Grenzen der Achse fest

Die AxisBound -Klasse repräsentiert eine minimale oder maximale Grenze von Achsenwerten. Bound kann als numerischer, Datums-/Uhrzeitwert oder als spezieller “Auto” -Wert angegeben werden.

Das folgende Codebeispiel zeigt, wie die Grenzen einer Achse festgelegt werden:

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);

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

// Clear demo data.
chart->get_Series()->Clear();

// Fill data.
chart->get_Series()->Add(u"AW Series 1",
                         System::MakeArray<System::String>({u"Item 1", u"Item 2", u"Item 3", u"Item 4", u"Item 5"}),
                         System::MakeArray<double>({1.2, 0.3, 2.1, 2.9, 4.2}));

chart->get_AxisY()->get_Scaling()->set_Minimum(System::MakeObject<AxisBound>(0));
chart->get_AxisY()->get_Scaling()->set_Maximum(System::MakeObject<AxisBound>(6));

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

So stellen Sie die Intervalleinheit zwischen Etiketten ein

Das folgende Codebeispiel zeigt, wie die Intervalleinheit zwischen Beschriftungen auf einer Achse festgelegt wird:

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);

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

// Clear demo data.
chart->get_Series()->Clear();

// Fill data.
chart->get_Series()->Add(u"AW Series 1",
                         System::MakeArray<System::String>({u"Item 1", u"Item 2", u"Item 3", u"Item 4", u"Item 5"}),
                         System::MakeArray<double>({1.2, 0.3, 2.1, 2.9, 4.2}));

chart->get_AxisX()->set_TickLabelSpacing(2);

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

So blenden Sie die Diagrammachse aus

Wenn Sie die Diagrammachse ein- oder ausblenden möchten, können Sie dies einfach erreichen, indem Sie den Wert der Eigenschaft set_Hidden festlegen.

Das folgende Codebeispiel zeigt, wie die Y-Achse des Diagramms ausgeblendet wird:

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);

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

// Clear demo data.
chart->get_Series()->Clear();

// Fill data.
chart->get_Series()->Add(u"AW Series 1",
                         System::MakeArray<System::String>({u"Item 1", u"Item 2", u"Item 3", u"Item 4", u"Item 5"}),
                         System::MakeArray<double>({1.2, 0.3, 2.1, 2.9, 4.2}));

// Hide the Y axis.
chart->get_AxisY()->set_Hidden(true);

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

So richten Sie die Diagrammbeschriftung aus

Wenn Sie eine Textausrichtung für mehrzeilige Beschriftungen festlegen möchten, können Sie dies einfach erreichen, indem Sie den Wert der Eigenschaft TickLabelAlignment festlegen. Das folgende Codebeispiel zeigt, wie die Etikettenausrichtung angekreuzt wird.

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>(inputDataDir + u"Document.docx");
System::SharedPtr<Shape> shape = System::DynamicCast<Shape>(doc->GetChild(NodeType::Shape, 0, true));
System::SharedPtr<ChartAxis> axis = shape->get_Chart()->get_AxisX();

//This property has effect only for multi-line labels.
axis->set_TickLabelAlignment(ParagraphAlignment::Right);

doc->Save(outputDataDir + u"WorkingWithChartAxis.TickMultiLineLabelAlignment.docx");
