stepSize is not working in chart js for line chart x-axis

See original GitHub issue

I am using below option in chart :

option : {
                    scales: {
                        xAxes: [{
                            display: true,
                            scaleLabel: {
                                display: true,
                                labelString: 'fpr',
                                fontStyle: 'bold'
                            },
                            ticks: {
                                callback: function(value, index, values) {
                                    return parseFloat(value).toFixed(2);
                                },
                                autoSkip: true,
                                maxTicksLimit: 10,
                                stepSize: .2
                            }
                        }],
                        yAxes: [{
                        	
                            display: true,
                            scaleLabel: {
                                display: true,
                                labelString: 'tpr',
                                fontStyle: 'bold'
                            },
                            ticks: {
                                callback: function(value, index, values) {
                                    return parseFloat(value).toFixed(2);
                                },
                                autoSkip: true,
                                 maxTicksLimit: 10,
                                 stepSize: .2
                            }
                        }]
                    }
                }

Also, the step size won’t work for the bottom because the default x axis is a ‘category’ axis that doesn’t interpolate numerically.

if you want to change that you can do

xAxes: [{
  type: 'linear',
  display: true,
  scaleLabel: {
    display: true,
    labelString: 'fpr',
    fontStyle: 'bold'
  },
  ticks: {
    callback: function(value, index, values) {
      return parseFloat(value).toFixed(2);
    },
    autoSkip: true,
    maxTicksLimit: 10,
    stepSize: .2
  }
}]
