Code to determine whether the browser supports SVG (partly cut from the Highcharts source code):

Js code: 

function hasSVG(){  
        SVG_NS = 'http://www.w3.org/2000/svg',  
    return !!doc.createElementNS &&           
                         !!doc.createElementNS(SVG_NS, 'svg').createSVGRect;  
}

IE8 does not support SVG, so when setting the legend horizontal position for the Highcharts chart, set the same x value, Chrome and IE The display effect is inconsistent. Therefore, it is necessary to determine whether the browser supports SVG and set different x values ​​according to different results.
