עבודה עם ChartSeries

Aspose.Words מאפשר למשתמשים לעבוד עם ChartSeriesCollection בכמה דרכים.

עבודה עם ChartSeriesCollection של תרשים

בואו נסתכל על אוסף ChartSeries. כל סדרות התרשימים זמינות דרך ChartSeriesCollection:

For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-C
// Get chart series collection.
System::SharedPtr<ChartSeriesCollection> seriesColl = chart->get_Series();
// Check series count.
std::cout << seriesColl->get_Count() << std::endl;

עבודה עם יחיד ChartSeries כיתה

הנה איך לעבוד עם סדרה מסוימת:

For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-C
// Get first series.
System::SharedPtr<ChartSeries> series0 = shape->get_Chart()->get_Series()->idx_get(0);

// Get second series.
System::SharedPtr<ChartSeries> series1 = shape->get_Chart()->get_Series()->idx_get(1);

// Change first series name.
series0->set_Name(u"My Name1");

// Change second series name.
series1->set_Name(u"My Name2");

// You can also specify whether the line connecting the points on the chart shall be smoothed using Catmull-Rom splines.
series0->set_Smooth(true);
series1->set_Smooth(true);

כל יחיד ChartSeries יש ברירת מחדל ChartDataPoint אפשרויות, אנא נסה להשתמש בקוד הבא כדי לשנות אותם:

For complete examples and data files, please go to https://github.com/aspose-words/Aspose.Words-for-C
// Specifies whether by default the parent element shall inverts its colors if the value is negative.
series0->set_InvertIfNegative(true);

// Set default marker symbol and size.
series0->get_Marker()->set_Symbol(MarkerSymbol::Circle);
series0->get_Marker()->set_Size(15);

series1->get_Marker()->set_Symbol(MarkerSymbol::Star);
series1->get_Marker()->set_Size(10);

איך לעבוד עם יחיד ChartDataPoint של ChartSeries

באמצעות ChartDataPoint ניתן להתאים אישית את העיצוב של נקודת נתונים אחת בסדרת התרשימים:

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

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

// Get first series.
System::SharedPtr<ChartSeries> series0 = shape->get_Chart()->get_Series()->idx_get(0);
// Get second series.
System::SharedPtr<ChartSeries> series1 = shape->get_Chart()->get_Series()->idx_get(1);
System::SharedPtr<ChartDataPointCollection> dataPointCollection = series0->get_DataPoints();

// Set explosion.
dataPointCollection->idx_get(0)->set_Explosion(50);

// Set marker symbol and size.
dataPointCollection->idx_get(0)->get_Marker()->set_Symbol(MarkerSymbol::Circle);
dataPointCollection->idx_get(0)->get_Marker()->set_Size(15);

dataPointCollection->idx_get(1)->get_Marker()->set_Symbol(MarkerSymbol::Diamond);
dataPointCollection->idx_get(1)->get_Marker()->set_Size(20);

// Add data point to the third point of the second series.
series1->get_DataPoints()->idx_get(2)->set_InvertIfNegative(true);
series1->get_DataPoints()->idx_get(2)->get_Marker()->set_Symbol(MarkerSymbol::Star);
series1->get_DataPoints()->idx_get(2)->get_Marker()->set_Size(20);
System::String outputPath = outputDataDir + u"WorkWithSingleChartDataPoint.docx";
doc->Save(outputPath);
