Determine if the browser supports SVG code (partially truncated from highcharts source):
JS Code:

Copy Code code as follows:

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 you set the legend horizontal position for the Highcharts chart, you set the same x value, and the display of chrome and IE is inconsistent. It is therefore necessary to determine whether the browser supports SVG and set different x values depending on the results.
