創建 PPTX 文件圖表 - C#
//Creating Charts in a Presentation
Presentation pres = new Presentation();
ISlide slide = pres.Slides[0];
//Creating the default chart
IChart chart = slide.Shapes.AddChart(ChartType.ScatterWithSmoothLines, 0, 0, 400, 400);
//Getting the default chart data worksheet index
int defaultWorksheetIndex = 0;
//Accessing the chart data worksheet
IChartDataCellFactory fact = chart.ChartData.ChartDataCellFactory;
//Delete demo series
chart.ChartData.Series.Clear();
//Add new series
chart.ChartData.Series.Add(fact.GetCell(defaultWorksheetIndex, 1, 1, "Series 1"), chart.Type);
chart.ChartData.Series.Add(fact.GetCell(defaultWorksheetIndex, 1, 3, "Series 2"), chart.Type);
//Take first chart series
IChartSeries series = chart.ChartData.Series[0];
//Add new point (1:3) there.
series.DataPoints.AddDataPointForScatterSeries(fact.GetCell(defaultWorksheetIndex, 2, 1, 1), fact.GetCell(defaultWorksheetIndex, 2, 2, 3));
//Add new point (2:10)
series.DataPoints.AddDataPointForScatterSeries(fact.GetCell(defaultWorksheetIndex, 3, 1, 2), fact.GetCell(defaultWorksheetIndex, 3, 2, 10));
//Edit the type of series
series.Type = ChartType.ScatterWithStraightLinesAndMarkers;
//Changing the chart series marker
series.Marker.Size = 10;
series.Marker.Symbol = MarkerStyleType.Star;
//Take second chart series
series = chart.ChartData.Series[1];
//Add new point (5:2) there.
series.DataPoints.AddDataPointForScatterSeries(fact.GetCell(defaultWorksheetIndex, 2, 3, 5), fact.GetCell(defaultWorksheetIndex, 2, 4, 2));
//Add new point (3:1)
series.DataPoints.AddDataPointForScatterSeries(fact.GetCell(defaultWorksheetIndex, 3, 3, 3), fact.GetCell(defaultWorksheetIndex, 3, 4, 1));
//Add new point (2:2)
series.DataPoints.AddDataPointForScatterSeries(fact.GetCell(defaultWorksheetIndex, 4, 3, 2), fact.GetCell(defaultWorksheetIndex, 4, 4, 2));
//Add new point (5:1)
series.DataPoints.AddDataPointForScatterSeries(fact.GetCell(defaultWorksheetIndex, 5, 3, 5), fact.GetCell(defaultWorksheetIndex, 5, 4, 1));
//Changing the chart series marker
series.Marker.Size = 10;
series.Marker.Symbol = MarkerStyleType.Circle;
pres.Save("AsposeScatterChart.pptx", SaveFormat.Pptx);
