Chart Rendering

Rendering Charts

Aspose.Cells APIs support to convert the Excel Charts to images and PDF formats without requiring any additional tools or applications. In order to provide rendering support, the Chart class has exposed ToImage & ToPdf methods with a verity of overloads to best suit the application requirements.

Rendering Charts to Images

The Chart.ToImage & ToPdf method has a verity of overloads to support simple as well as advanced rendering. If the application requirement is to render the chart in its default dimensions, we suggest you use the Chart.ToImage method as follow.

It is also possible to render the charts to images with advanced settings. Aspose.Cells APIs have exposed an overload version of Chart.ToImage method that could accept an instance of ImageOrPrintOptions, while allowing to specify parameters such as resolution, smoothing mode, image format and so on.

Rendering Chart to PDF

In order to render the chart to PDF format, the Aspose.Cells APIs have exposed the Chart.ToPdf method with the ability to store the resultant PDF on disc path or Stream.
