Essential Presentation provides support to create and modify Column Clustered Charts. The below assemblies are needed to execute the code explained below,
The below code example illustrates creating a PowerPoint presentation and adding a blank slide. //Create presentation with empty slides. IPresentation presentation = Presentation.Create(); //Add blank slide into the presentation ISlide slide = presentation.Slides.Add(SlideLayoutType.Blank);
The below code example illustrates creating a chart and adding the related chart data. //Add chart to the slide with specified size and positions. IPresentationChart chart = slide.Shapes.AddChart(100, 100, 640, 427); //Sets value to the chart's worksheet. chart.ChartData.SetValue(2, 1, "Category 1"); chart.ChartData.SetValue(3, 1, "Category 2"); chart.ChartData.SetValue(4, 1, "Category 3"); chart.ChartData.SetValue(5, 1, "Category 4"); chart.ChartData.SetValue(1, 2, "Series 1"); chart.ChartData.SetValue(2, 2, 4.3); chart.ChartData.SetValue(3, 2, 2.5); chart.ChartData.SetValue(4, 2, 3.5); chart.ChartData.SetValue(5, 2, 4.5);
//Set chart type as Column_Clustered. chart.ChartType = OfficeChartType.Column_Clustered; The below code example illustrates setting the chart type.
The below code example illustrates adding a serie to the chart and setting the serie range. //Add first serie to chart series collection with specified serie name.
IOfficeChartSerie serie1 = chart.Series.Add("Series 1");
//Sets values to first serie.
serie1.Values = chart.ChartData[2, 2, 5, 2];
The below code example illustrates adding category label values from chart data. //Sets values to category labels of primary category axis. chart.PrimaryCategoryAxis.CategoryLabels = chart.ChartData[2, 1, 5, 1];
The below code example illustrates setting overlap and gap width for the Column Clustered chart. //Seta value to gap value between series. serie1.SerieFormat.CommonSerieOptions.Overlap = -27; //Sets Width of the series serie1.SerieFormat.CommonSerieOptions.GapWidth = 219;
The below code example illustrates saving the created presentation to a file. //Saves the presentation with specified file name with extension.
presentation.Save("ColumnClusteredChart.pptx");
