            formatter: "{value}"
        },
        axisLine: {
            lineStyle: {
                color: this.colors[0]
            }
        },
        gridIndex: 0,
        min: -1,
        max: 6,

Code No problem
are you sure you only changed the values of these two attributes and nothing else?

I have the same problem. I got better after upgrading echarts.min.js

max:function (value) {

                    
                        return value = 6;
                     },
                    min:function (value) {
                        return value = -1;
                   }
