[Solved]-Remove Highcharts dataLabel border-Highcharts

i had the same problem with a column chart. i've solved the issue by using this in my plotoptions.column:

datalabels: {
    /* ... */,
    style: {
        textshadow: null
    }
}

does it work for you ?

this did the job for me:

plotoptions: {
        series: {
          datalabels: {
            style: {
              textoutline: 0,
            }
        }
    }
}

you sure can. see the api docs here regarding datalabels. to remove the border set:

    datalabels: {
    ...
    borderwidth: 0,
    ...
    },

if you are talking about the text shadows you can do this in your datalabel as well:

            datalabels: {
                enabled: true,
                fontsize: '20px',
                color: 'yellow',
                borderwidth: 0,
                format: '{point.properties.name}',
                style: {
                    textshadow: false
                }
            },

highcharts v5 code for fixing this is

datalabels: {
  style: {
    textoutline: 0
  },
}
