Export a Highcharts chart as a picture or PDF document

Instance:

function Brandpie (args_datetime) {

var Demis=window.document.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 ({

Chart: {

Renderto: ' ContainerPie2 ',

Plotbackgroundcolor:null,

Plotborderwidth:null,

Plotshadow:false

},

Title: {

Text: ' Test '

},

Subtitle: {

Text: "Date:" +args_datetime,

X:-20

},

ToolTip: {

Percentagedecimals:2,

Pointformat: ' {series.name}:{point.percentage}% ',

},

Credits: {

Enabled:false,

} ,

exporting:{

filename: ' Test ',

URL: ' chart/doexport.action ',

                  },

Plotoptions: {

Pie: {

Allowpointselect:true,

Cursor: ' pointer ',

DataLabels: {

Enabled:false

},

Showinlegend:true

}

},

Series: [{

Type: ' Pie ',

Name: ' Percentage ',

Data:piedata

}]

});

}

});

}

In the example above: theexporting property is primarily used with an export, where filename represents the file name everywhere, and the URL represents the action that the export handles. The default request passes a parameter of type: Indicates the file type (. jpg/pdf) to export filename: Represents the exported file name; SVG: represents some of the parameters when exporting.
