Each nested array contains component instances that should be in the same row in the exported document. In this demo, chartInstance
and pieChartInstance
occupy the only row in the document.
The options parameter accepts an object whose fields allow you to configure export properties. In this demo, we specify the fileName
and format
. Refer to the method description for information on other available fields.
