Render Highcharts canvas as a PNG on the page

Here's a hack if you have your heart set on using HighCharts. It uses canvg to parse the SVG into a canvas and then converts the canvas to a PNG.

chart = new Highcharts.Chart({
    
    chart: {
        renderTo: 'container'
    },
    
    title: {
        text: ''
    },
    
    xAxis: {
        categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
    },
    
    series: [{
        data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]        
    }],
    
    navigation: {
        buttonOptions: {
            align: 'center'
        }
    }
});

canvg(document.getElementById('canvas'), chart.getSVG())
    
var canvas = document.getElementById("canvas");
var img = canvas.toDataURL("image/png");

document.write('<img src="'+img+'"/>');

I know this is now an old question, but since it came up #1 for me in a Google search result, I think it's worth mentioning that Highcharts now natively supports a server-side image generation script and it works great.
