Chart to PDF with Golang via C++
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 a disk path or stream.
Create Chart PDF with Desired Page Size
You can create a chart PDF with your desired page size using Aspose.Cells and specify how you want to align the chart inside the page—top, bottom, center, left, right, etc. Besides, the output chart can be created in a stream or on disk. Please see the following sample code that loads the sample Excel file, accesses the first chart inside the worksheet, and then converts it into output PDF with the desired page size. The following screenshot shows that the page size in the output PDF is 7 × 7 as specified in the code, and the chart is center‑aligned both horizontally and vertically.
