Thank you for the tip.  This mostly addresses what I was looking for, 
similar to original poster.

I'm not sure if you have already figured this out, but there is an 
extremely simple solution.

This page has instructions for adding an annotation which did the job for 
me:

Add or edit a trendline or annotation 
> 
>

The annotation allowed me add a note to any existing X or Y axis point.
Want to put it somewhere else?  Just add another row or column.

Hope this helps (5 yrs later)

Hi Richard,

That was a perfect solution for what I was looking for. Its also worth 
noting that you can use this to do horizontal lines as well, or a 
crosshair, through adding a trend line instead of a error bar.

Thanks

You may consider the use of error bars.  I carried this trick over from 
Excel.  

1) Add another column to your chart in Advanced Edit, Recommendations, Data 
Range.  
2) Add a number to a cell in that column within your Y-axis range 
corresponding to the location of your vertical line. 
3) In Advanced Edit, Customization, Series, pick your newly created column. 
  You can add an error bar for the cell you chose in 2) by going to the 
Error Bars and selecting Constant from the Error Bar drop down menu.
4) Extend the error bar as high and low as you want.  You can fix the 
Y-Axis range if your error range raises or lowers the chart Y range.

I hope this helps!

hi, asgallant,

I can't figure out how to use domain-axis annotation to draw a vertical 
line, can you explan how to do that?

 Oh, I forgot - you can use domain-axis annotations to do this.  See column

 details implementing these.

No, there is no support for this in Line or Area charts.  If you use 
scatter charts, you can make something that looks very similar to a line 
chart, and you can put a vertical line in that.  I helped someone else here 
do something similar in ScatterCharts:
