I a trying to draw a reference line at 16 n this graph.
I am recording the voltage of solar panels during different months and 16 is the absolute minimum so am wanting to see times above and below a reference line

The easiest way would be to add the value 16 in column F on every row then add F2:F73 as a new series on the chart
