Export Chart to SVG with viewBox attribute
By default, when the chart is export to SVG format, the viewBox attribute is not included in its XML. However, Aspose.Cells provides ImageOrPrintOptions.setSVGFitToViewPort() property which when set to true exports the chart to SVG with viewBox attribute.
If you open the chart’s SVG in notepad, you will find the viewBox attribute similar to this.
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="100%" height="100%" viewBox="0 0 480 288">
