Export Several Charts

Documentation

This demo shows how to export several charts into a single image using the DevExpress.viz.exportFromMarkup method. Before calling this method, you need to collect the SVG markup of all charts using the DevExpress.viz.getMarkup method and calculate the size of the resulting image.
