Manfred this one was a little tricky and I'm not sure if my [xAxis],
[yAxis] idea would have worked on this particular request, but anyways
here's how to do it. Place this bit of code in the line you have red above.
options.yAxis[this_yAxis].plotLines = [{
value: 1013,
color: '#FF0000',
width: 2,
}]
Change the color (right now it's red) and the width.
You will also need to grab the latest development Belchertown dark CSS file
<https://raw.githubusercontent.com/poblabs/weewx-belchertown/development/skins/Belchertown/belchertown-dark.min.css>
since I had to make some changes to it for the line to appear in dark mode.
Note: backup your current dark CSS file just in case.
