## **Sequence Diagram**
Shows the core flow where transformProps detects time-comparison (derived)
series—including exact-name matches—computes a visible dash pattern per offset,
sets connectNulls, picks the original series for color matching, and emits the
final ECharts series configuration.
```mermaid
sequenceDiagram
participant TransformProps
participant isDerivedSeries
participant TimeCompareLookup
participant getTimeOffset
participant EChartsOptions
TransformProps->>isDerivedSeries: Ask "is this a derived (time-compare)
series?" (passes series, formData, seriesName)
isDerivedSeries->>TimeCompareLookup: Check hasTimeOffset OR exact
time_compare includes seriesName
TimeCompareLookup-->>isDerivedSeries: true/false (derived)
isDerivedSeries-->>TransformProps: derived? (boolean)
alt derived
TransformProps->>getTimeOffset: resolve offset for series
(getTimeOffset(entry, time_compare) || seriesName)
getTimeOffset-->>TransformProps: offset key
TransformProps->>TransformProps: assign visible dash pattern and
opacity per offset; set connectNulls = true
TransformProps->>TransformProps: find original series for color
matching when seriesName is an exact time offset
TransformProps-->>EChartsOptions: emit series entry (name,
lineStyle: [dash,gap], opacity, connectNulls, colorScaleKey)
else not derived
TransformProps-->>EChartsOptions: emit series entry without dashed
styling
end
```
