Any reason for overwriting series here, and not where it's defined?

const timeseries = kpis.map((kpi) => ({
title: kpi.name,
color: kpi.color,
type: 'areaStacked',
data: timeseriesPerSubtype[kpi.name],
hideLegend: true,
}));

asPercent is defined in /public and I think the server doesn't have to know how the UI is going to show the value, it should only provide the value. I have my concerns about color, type and hideLegend, maybe they should all be removed from the server and be defined only in the client.

I think the server doesn't have to know how the UI is going to show the value, it should only provide the value.

It depends. Are there any drawbacks to defining it on the server? I see clear drawbacks in defining the chart config across multiple files.
That being said, if it's too much of a hassle because it'll require you to move asPercent and its dependencies to the server I'm fine with leaving it as-is.

@smith Regarding #70161: I'd be surprised if we don't have a way to access the advanced settings from the server.

Thanks for your input @sqren, the only drawback I can see here is that I'd have to move the asPercent to a common place. But if it makes sense the server to send the value already formatted then I wouldn't think it as a drawback but as an improvement. My question is does it make sense sending the value already formatted from the server? For what I've seen we never send any formatted value from the server, we always leave this responsibility to the client.

FYI: I'm not against moving the asPercent, I only want to keep consistency across all APIs we've got.

@smith: why? (Other than it being the convention)

On a technical level, some explanation is in #70161. If a users are using different themes and the API includes the colors of the lines the API would have to return different responses based on the theme.

If the presentational elements are coupled with the chart data, changing the presentation becomes more difficult.

For theming then it makes sense, although I can imagine that can be supported on the server as well. Personally I'm not swayed by "presentational data belongs on the client". IME, server-side code is more predictable and testable, and it's nice to have it in one place.

well, for now then I'll move the asPercent to the common directory and return the value already formatted from the server. We can continue discussing on Nathan's issue #70161.
