As decided with @teresaalvarezsoler, we are removing from the scope of this change the tour. We always had changes in defaults in the past, it important to specify them in the release note but for now we don't need a tour to highlight that change. |

Problem
When there are missing time buckets in a time series chart, we show the isolated data points as empty circles. However, this way of displaying the data is very hard to read and often confusing.
Solution
The solution is described in detail here. In summary:
Communicating the change to users
We should add a tour that communicates the change to users and let them know how to change the behaviour if they want to. The tour will appear when a user creates a new line chart (regardless of whether it has missing time buckets?).
(exact wording TBD)
Existing charts
We would like to keep existing charts as untouched as possible, but we don't want to introduce two chart styles while we know the current behaviour is not readable and confusing. Therefore, we decided to:
For the charts that change, we will show a tour letting users know about the change and how they can revert it back. The tour will be shown per user the first time they view a chart that changed which can happen either in one of these two places: 1) at the dashboard level (if there are multiple charts, only for the first chart) or 2) in the Lens editor
(exact wording TBD)
