Add bullet points to Time Series Chart

How do I add bullet points to a trendline on a time series chart trend? I assume it's supported since it's shown in d3's documentation on trends' interpolation that the Inductive Docs links to.

The way I got mine to work was adding a duplicate trend item set as a "scatter type". if you leave all the other props the same it gives the same effect.


This is a very clever way.

when adding another trend, at the legend display, it will have a duplicate legend how do you get rid of it?

I ended up turning the legend visibility off and creating my own legend. I did a script to dynamically add the correct number of "legend items" and set their color based on the original trend column items.
