I am a user who used to provide a custom dashboard using the v1 API. However, the page that provided guidance on building a custom dashboard seems to have been removed, making it difficult to maintain the dashboard I previously developed. I would appreciate any help you can provide.
Here is an example of the HTML I am using:
I would like to know how to perform a sum aggregation with `group by` using this setup.
I’d like to inquire about this issue with your support team. Could you help translate this into English?

The [files are available on GitHub under the v2.2.3 tag](https://github.com/netdata/netdata/tree/v2.2.3/src/web/gui/custom). Please note that the legacy dashboard has been removed in nightly releases (as was [announced in v2.2.0](https://github.com/netdata/netdata/releases/tag/v2.2.0#v220-deprecation-notice)), while the legacy API will be maintained until the next major release.
