[Solved]-Highchart spline Cut Off when reach to maximum scale value. How can it fixed?. I have attached may sample code on body-Highcharts

i think the cut line comes from the fact that you have a 5px linewidth in your config. so in order to have the line not cut, you need to put it a 3px below where it is now, so that it has 2 pixels on top available (2pixels top + 2 pixels bottom + its pixel position = 5 pixels).

let b = [97,97,97];

note that you could also increase the max size of your graph (yaxis.max): https://jsfiddle.net/sk4n9gp0/

setting the series.clip as a false is a solution which you are looking for.

chartdata.push({
    clip: false,
  name: 'b',
  type: 'spline',
  date : 'b',
  data : b,
  color: 'blue'
});
