Chart interpolation

If you see the attached image

The first tag is interpolated linearly, but the other two are interpolated stair step. I did nothing different for each one, so how can I control the interpolation type with the chart component?

This looks like it might be related to a bug ticket I just filed.
Are these populated by a tag history query? I don’t have a workaround yet, but I’ve added you to the internal bug ticket so I’ll hopefully remember to update this thread once there’s an update on the ticket.

Yes, the chart information is populated by a tag history query.

How long does a bug ticket takes to be solved?
