[Solved]-Highcharts missing bars when running through PhantomJS-Highcharts

it was because of the highcharts animation when the bars are initialized.

actually i had the animation disabled in the chart configuration, like:

    $('#container').highcharts({
    chart: {
        type: 'bar',
        animation: false
    },

but this seems not to be enough. the animation must be disabled explicitly for the chart type:

    plotoptions: {
        bar: {
            animation: false,
            enablemousetracking: false
        }
    }
