[Solved]-Get Highcharts width-Highcharts

This is an old question so my answer is just to provide more options for those who are checking this later.

If you want full width of chart:

this.chart.chartWidth

If you want the chart xAxis width, without possible labels on the left (check image), you have two options:

this.chart.plotWidth // or
this.chart.xAxis[0].width

You could use the xAxis extreme.max and translate it to pixels. Something like (not tested):

Chart.xaxis[0].toPixels( chart xaxis[0].getExtremes().max )

It feels like there should be an easier way, but I guess I would have used the containing div width. Maybe you could use chart options to get the containing div I'd and get the width from that.

In chart object you have access to chartWidth parameter, which keeps width of chart.

//callback
    function(chart){

                console.log(chart.chartWidth);

            }
