[Solved]-How can i have the same radius for each point of series with hover?-Highcharts

i solved...

to remove that shadow around a point when hover, i must to add this:

plotoptions: {
            series: {
                states:{
                    hover:{
                        halo: false
                    }
                }
            }
    },

halo: false

while if you want, is possible to customize halo:
