## Context
- Updates the BarChart in our design system to support multi series in a
similar fashion to how the LineChart already supports multi series
- Update chart renderer in explorer notebooks to support multiple Y axes
using the `MultiSelector` component
- Up to 3 y columns can be selected for now (Arbitrary limit from a
color's selection POV but also just felt like anything more and the
chart doesn't feel useful)
- Only linear scale will be supported if multiple y columns are selected
(Will switch back to linear if originally on log scale)

## Summary by CodeRabbit
* **New Features**
* Charts now support selecting and displaying up to three Y-axis data
series.
* Bar and line charts render multiple series with distinct colors.
* Cumulative calculations work independently across multiple selected
series.
* Chart controls provide clearer responsive layouts and limit selections
appropriately.
* **Bug Fixes**
* Logarithmic scaling automatically switches to linear when multiple
series or unsupported values are selected.

## Context
Related to Explorer / Notebooks - this adds chart functionality for the
Query cells

/>
Query results can be rendered as either bar or line chart - using the
chart packages from `ui-patterns`
[NOTE]: For design team reviewers - am patching the chart packages to be
agnostic to the `timestamp` property within the provided data set. Would
love to use this component from a consistency POV instead of the old
`BarChart` component we have.
Have intentionally omitted log scale functionality from this PR - will
have that separately 🙏

cumulative values, and label visibility.
- Added configurable X-axis support for charts.
- Display preferences are saved with each notebook cell.
- **Improvements**

## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.
YES
## What kind of change does this PR introduce?
Fixes Edge Function Execution Time chart within our observability
reports time formatting. This also fixes the non-hovered state which
would lose the `ms` formatting.

## Summary by CodeRabbit
* **New Features**
* Improved execution-time chart formatting with clearer millisecond
values, thousands separators, and configurable precision.
* Chart highlights now support custom value formatting alongside
existing number, percentage, and byte formats.
* **Bug Fixes**
* Non-finite execution-time values now display safely as `0ms`.

Fixes: #47377
## What is the current behavior?
Enabling **Cumulative** on a results chart concatenates Y-axis values
instead
of summing them whenever the column is a `bigint`, `numeric`, `money`,
or
`count(*)` aggregate — which Postgres returns as JSON strings. For
per-row
values `10, 20, 30` the chart plots `10, 1020, 102030`.
`getCumulativeResults` ran `(prev[yKey] || 0) + row[yKey]` on raw result
rows.
The Y-axis selector explicitly allows numeric-string columns, so this is
a
common, fully-supported path (e.g. any `count(*) ... group by`).
## What is the new behavior?
Both operands are coerced with `Number()` before the addition, keeping
the
existing `|| 0` fallback for null/undefined/non-numeric values. The
series now
sums correctly: `10, 30, 60`.
The cumulative logic was previously duplicated in `ChartConfig.tsx` and
`QueryBlock.utils.ts` (which is how this bug slipped in twice). It is
now a
single shared, tested helper: `getCumulativeResults` lives in
`QueryBlock.utils.ts`, and `ChartConfig.tsx` imports it instead of
re-declaring
its own copy. The shared helper's `ChartConfig` type import is `import
type` to
avoid a runtime circular dependency, and its signature accepts
`readonly` rows
so both call sites type-check.
## Additional context
- Added regression tests for numeric-string inputs and for
null/undefined/non-numeric fallback to `0`. The existing tests only
covered
literal `number` inputs, never the string form Postgres actually
returns.
- Verified the new tests fail against the old code (`y: '010'`,
`'05undefined'`)
and pass with the fix. Full `QueryBlock.utils.test.ts` suite: 18
passing.
No migrations, no API changes, no infra changes.

## Summary by CodeRabbit
* **Bug Fixes**
* Fixed cumulative chart calculations so numeric values are always added
correctly, even when results arrive as strings.
* Improved handling of empty or non-numeric values in cumulative totals
so they are treated as zero instead of breaking the sum.
* **Tests**
* Added coverage for cumulative result calculations with numeric strings
and missing values.
