Function renderMetricBars

renderMetricBars<TMetric extends MetricBarItem>(
options: RenderMetricBarsOptions<TMetric>,
): string
Renders aligned labeled progress rows.

This pure renderer composes renderProgressBar; it does not import Blessed. Import from blessed-components/metric-bars to keep the Blessed adapter outside the module graph.

Output with a heading:
```
[label] [value]

[padded metric label] [track] [formatted value]
```
Type Parameters
- TMetric extends MetricBarItem
  Metric shape, including optional application metadata.
Parameters
- options: RenderMetricBarsOptions<TMetric>
  Shared range, track settings, metrics, and optional heading.
Returns string
Plain text without ANSI sequences or Blessed tags.
Throws
RangeError Propagates invalid width, range, character, or metric value errors from renderProgressBar.
Example
```
import { renderMetricBars } from 'blessed-components/metric-bars';

renderMetricBars({
  barWidth: 16,
  label: 'Overall',
  value: '85%',
  metrics: [
    { label: 'Quality', value: 78 },
    { label: 'Popularity', value: 99 },
  ],
});
```
Example: Typed metadata
```
renderMetricBars({
  barWidth: 10,
  metrics: [{ label: 'Latency', value: 25, unit: 'ms' }],
  formatValue: ({ metric, value }) => `${value}${metric.unit}`,
});
```
