Recharts component to PNG

Question

I currently have a Recharts component that I would like to export as a PNG file.

Answer 1

I was able to solve my problem by delving into the Recharts component. Recharts renders as an SVG under a wrapper so all I had to do was convert properly to save as both HTML or SVG

// Exports the graph as embedded JS or PNG
exportChart(asSVG) {

    // A Recharts component is rendered as a div that contains namely an SVG
    // which holds the chart. We can access this SVG by calling upon the first child/
    let chartSVG = ReactDOM.findDOMNode(this.currentChart).children[0];

    if (asSVG) {
        let svgURL = new XMLSerializer().serializeToString(chartSVG);
        let svgBlob = new Blob([svgURL], {type: "image/svg+xml;charset=utf-8"});
        FileSaver.saveAs(svgBlob, this.state.uuid + ".svg");
    } else {
        let svgBlob = new Blob([chartSVG.outerHTML], {type: "text/html;charset=utf-8"});
        FileSaver.saveAs(svgBlob, this.state.uuid + ".html");
    }
}

I am using FileSaver.js for the save prompt.
