Hello kiencao42!

Welcome to our forum and thanks for contacting us with your question!

I'm not sure if I understood you correctly. Do you want to draw a horizontal line, from the beginning of the chart to its end?

If yes here you've got an example demo of how it can be done: https://jsfiddle.net/BlackLabel/28jkvuno/

API references: https://api.highcharts.com/highcharts/yAxis.plotLines

If no, please provide me some sketches or images how it should look like.

Best regards!
