Export highcharts charts as images or PDF documents

Instance:

Function brandpie (args_datetime ){

VaR demis=windodoc ument. getelementbyid ("first"). value;

VaR chart;

$. Ajax ({

Type:
"Post ",

Data: {demision: "3", querydate: args_datetime },

URL: "report/dogetitempieorcolumn. Action? Querytype = "+ querytype,

Success: function (data)
{

VaR jsonarray = eval ('+ Data + ')');

VaR piedata = jsonarray. Data;

Chart = new highcharts. Chart ({

},

Title :{

Text:

Exporting :{

Filename: 'test ',

},

Plotoptions :{

});

}

In the above example:The exporting attribute is mainly used and exported. filename indicates the name of the file that is everywhere, and URL indicates the action to be exported. The default request parameter isType: exported file (.jpg/PDF)
Filename: indicates the exported file name; SVG: indicates some parameters during export.
