How to always show the plotLine in HighCharts?

Question

I am creating a HighChart with a plotLine in it. The plotLine has a fixed value, while the data can vary between charts.

HighChart scales the y-axis automatically ba

In some cases, wergeld's solution would be preferable than jank's solution, especially when you are not sure about min and minRange. But wergeld's solution has a minor issue. If you point your mouse over the plot line, it will show a point and tooltip on the point. To avoid this, I have modified his solution and added enableMouseTracking to get rid of the problem.

{
     name: 'Goal',
     type: 'scatter',
     marker: {
          enabled: false
     },
     data: [450],
     enableMouseTracking: false
}
