Hi @mengweieric @btzeng @anirudha

We explored dimension and metrics implementation with the reference of superset charts and issue opensearch-project/dashboards-observability#125.
As per our Understanding:

• There should be interval selector UI for dimensions like (year, month, days, ....)
• Along with the fields selector there should be input fields to take interval as a number in dimension
• No need for aggregation methods in dimension if it's a time-series chart
• for metrics, there should be one label and custom_label fields to achieve customized ppl query

Please provide us with more insights for Query Manager and Query manager API.
