What is the problem or goal the end user is trying to solve or accomplish?
The end user needs to add horizontal benchmark lines or other time series annotations to a "Line Chart" visualization. Currently, they are limited to using the "Time Series Line Chart (Legacy)" as the only available source for time series annotation layers. However, since this legacy chart type is deprecated, there is concern about its future support and the need for continuity in annotation capabilities for modern charts.
How are they solving it currently?
To add annotations to a "Line Chart," users must create a separate "Time Series Line Chart (Legacy)" solely as the annotation source, even though this chart type is deprecated. This workaround is functional but requires users to maintain legacy charts, creating redundancy and raising questions about long-term support as legacy features are phased out.
What is the recommended solution by the Customer?
The customer recommends allowing the new "Line Chart" (or any other modern chart type) to be selected as an annotation source for the "Time Series Annotation Layer Type." This would enable users to continue using time series annotations without relying on deprecated charts, ensuring consistency and future-proofing the annotation functionality.
