Presentation charts are used to display important information with huge data and it is easy to catch readers’ eyes. There are many different types of data charts, such as column charts, bar charts, line charts, pie charts, scatter charts, doughnut charts and combination charts in PowerPoint slides. In this article we will show clearly how to create a chart in a PowerPoint document using Free Spire.Presentation for Java.
This article contains the following two parts:
*Create a single column chart in PowerPoint.
*Create a combination chart with column chart and line chart in PowerPoint.

chart.getSeries().get(2).getFill().getSolidColor().setKnownColor(KnownColors.LIGHT_BLUE);

A combination chart is a chart that combines at least two chart types in a single chart, this example will show a combination chart with column chart and line chart.

Conclusion
Thanks to Free Spire.Presentation for Java, I’m able to show you how to insert presentation chart programmatically in Java. I hope you could have a deeper understanding of chart tools on presentation slides after reading my article. Thanks for reading.
