Summary

Bug Report: DatasetComponent not registered, causing dataset configuration to be ignored in ECharts 6

Summary

After upgrading to @siemens/charts-ng v48+ (which includes ECharts 6.0.0), chart options using the dataset configuration are silently ignored. Scatter data points and other data specified via dataset.source are not rendered, and no error is logged to the console.

Root Cause

ECharts 6.0.0 introduced stricter tree-shaking, requiring explicit registration of all components via echarts.use(). The library registers chart types (ScatterChart, LineChart, etc.) and various components (GridComponent, LegendComponent, MarkLineComponent, etc.), but DatasetComponent is not registered.

Files affected:

• projects/charts-ng/chart/si-chart.component.ts (lines 34-55)
• projects/charts-ng/cartesian/si-chart-cartesian.component.ts (lines 44-61)

Without DatasetComponent, the dataset option in chart configuration is silently ignored by ECharts.

Current Workaround

Consumers can register DatasetComponent themselves before using the chart:

import { DatasetComponent } from 'echarts/components';
import * as echarts from 'echarts/core';

echarts.use([DatasetComponent]);

Recommended Fix

Register DatasetComponent in the library's chart components:

projects/charts-ng/chart/si-chart.component.ts:

import { DatasetComponent } from 'echarts/components';

echarts.use([
  // ... existing registrations
  DatasetComponent,
  LegendComponent,
  // ...
]);

projects/charts-ng/cartesian/si-chart-cartesian.component.ts:

import { DatasetComponent } from 'echarts/components';

echarts.use([
  // ... existing registrations
  DatasetComponent,
  LegendComponent,
  // ...
]);

Additional Context

The DatasetComponentOption type is already exported from echarts.model.ts, indicating the library intends to support dataset configuration. This was simply missed during the ECharts 6 migration.

### Version

@siemens/charts-ng: >= 48.0.0

### Steps to reproduce

```typescript
// Component using dataset configuration
chartOptions: ECBasicOption = {
  dataset: {
    source: [
      { x: 10, y: 20 },
      { x: 15, y: 35 },
    ],
  },
  series: [
    {
      type: 'scatter',
      // No explicit data array - relies on dataset
    },
  ],
  xAxis: { type: 'value' },
  yAxis: { type: 'value' },
};

What is the current bug behavior

No scatter points are rendered. The chart appears empty with no console errors.

What is the expected correct behavior

Data from dataset is displayed correctly.

@akashsonune @dr-itz I would follow the recommendation or do you a different opinion?

Agree, I think it is simply missed during the structuring of the new charts entry points.

[StNimmerlein]

I just noticed that CustomChart is also missing and no longer imported by element so we have to use the same workaround here as well.

ok let me go through all the types that we didn't import
