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
You need to add in a point to you chart but disable the marker. I added a new series with scatter plot type and its value equal to the goal value:
{ name: 'Goal', type: 'scatter', marker: { enabled: false }, data: [450] }
