How to Create & Embed Excel Chart as OLE Object in PPTX Presentation Using Java
This technical tip shows how java developers can create Excel chart and embed it in presentation as OLE object using Aspose.Slides for Java. In PowerPoint Slides, the use of editable chats for graphical display of the data is a common activity. Aspose provides the support of creating the Excel Charts with the use of Aspose.Cells for Java and further these charts can be embedded as an OLE Object in the PowerPoint Slide through Aspose.Slides for Java. This article covers the required steps along with the implementation in Java to create and embed an MS Excel Chart as an OLE Object in PowerPoint presentation by using Aspose.Cells for Java and Aspose.Slides for Java.
