[Solved]-Highcharts - yAxis logarithmic scale and allowDecimals set to false not seeming to have any effect-Highcharts

i found this configuration worked for me:

  yaxis: {
    gridlinecolor: 'transparent',
    allowdecimals: false,
    type: 'logarithmic',
    tickinterval: 0.1,
    startontick: false,
    linewidth: 0,
    gridlinewidth: 0,
    minorgridlinewidth: 0
  },

bear in mind that the tickinterval property works differently for logarithmic axes, i.e. 1 would be a label at every power of 10, so for this data set at least you want an interval of 0.1
