Inserting charts to your PPT document is an easy and eye catching way to display important information. Spire.Presentation includes many different types of data charts including column charts, cylinder charts, cone charts, pyramid charts, clustered charts, line charts, pie charts, bar charts, area charts, scatter charts, stock charts, surface charts, contour charts, doughnut charts, bubble charts and radar charts.
Spire.Presentation for .NET, a reliable .NET PPT component, enables you to generate, read, edit, convert even print your PPT documents without installing Microsoft PowerPoint on your machine. Using Spire.Presentation for .NET, you also can insert charts in your PPT document with C#. Please see the target PPT document with chart as below picture:
The steps of method are:
Step 1: Create the PPT document.
Presentation presentation = new Presentation();
Step 2: Insert chart, set title and style of the chart.
RectangleF rect = new RectangleF(presentation.SlideSize.Size.Width / 2 - 200, 100, 400, 400); IChart chart = presentation.Slides[0].Shapes.AppendChart(Spire.Presentation.Charts.ChartType.Cylinder3DClustered, rect); chart.ChartTitle.TextProperties.Text = "Report"; chart.ChartTitle.TextProperties.IsCentered = true; chart.ChartTitle.Height = 30; chart.HasTitle = true;
Step 3: Prepare data for the chart. Load a simple DataTable from XML file via LoadData() method.
DataTable dataTable = LoadData();
private DataTable LoadData()
{
DataSet ds = new DataSet();
ds.ReadXmlSchema("data-schema.xml");
ds.ReadXml("data.xml");
return ds.Tables[0];
}
Step 4: Attach the data to chart. We can use chart.ChartData[rowIndex, columnIndex] to get/set the value of the specified cell in the data table of chart. Using the property chart.ChartData[rowIndex, columnIndex].Text to get/set the text value. Using the property chart.ChartData[rowIndex, columnIndex].Value to get/set numeric value. In this article we define a method InitChartData to attach the Data of the chart.
private void InitChartData(IChart chart, DataTable dataTable)
{
for (int c = 0; c < dataTable.Columns.Count; c++)
{
chart.ChartData[0, c].Text = dataTable.Columns[c].Caption;
}
for (int r = 0; r < dataTable.Rows.Count; r++)
{
object[] data = dataTable.Rows[r].ItemArray;
for (int c = 0; c < data.Length; c++)
{
chart.ChartData[r + 1, c].Value = data[c];
}
}
}
Step 5: Set the Series label and Category label.
chart.Series.SeriesLabel = chart.ChartData["B1", "D1"]; chart.Categories.CategoryLabels = chart.ChartData["A2", "A7"];
Step 6: Assign data to each Series and set each Series' fill color.
chart.Series[0].Values = chart.ChartData["B2", "B7"]; chart.Series[0].Fill.FillType = FillFormatType.Solid; chart.Series[0].Fill.SolidColor.KnownColor = KnownColors.Brown; chart.Series[1].Values = chart.ChartData["C2", "C7"]; chart.Series[1].Fill.FillType = FillFormatType.Solid; chart.Series[1].Fill.SolidColor.KnownColor = KnownColors.Green; chart.Series[2].Values = chart.ChartData["D2", "D7"]; chart.Series[2].Fill.FillType = FillFormatType.Solid; chart.Series[2].Fill.SolidColor.KnownColor = KnownColors.Orange;
Step 7: Set the 3D rotation.
chart.RotationThreeD.XDegree = 10; chart.RotationThreeD.YDegree = 10;
Step 8: Save the document.
presentation.SaveToFile("chart.pptx", FileFormat.Pptx2010);
