If you want to add a horizontal line to a ColumnChart, you need to use a ComboChart<https://developers.google.com/chart/interactive/docs/gallery/combochart>, and add an additional data series with data points for the line. Use the series.<series index>.seriesType option to tell the chart what to use for each series. Type "line" draws a line and type "bars" draws columns.
