Here’s a chart:
Link to it in the chart maker:
If I load the chart in the full editor, you can see there’s code for a vertical line annotation:
However, as you can see, the vertical line isn’t showing up.
I’ve gotten horizontal line annotations to work as shown here:
And vertical line annotations to work on linear axis charts:
But for some reason, it isn’t showing up in the example above.
Any suggestions welcome.
I believe the explanation here is that the interactive Chart Maker/Chart Viewer doesn’t include support for annotations at this time. Your configurations look fine otherwise. This is something we can look into upgrading…

The key was, the value of the annotation has to match one of the x-axis values exactly.
So I guess the new feature request is: allow annotation values that are arbitrary (instead of having to match an existing value).
