Interface: OptsChartData

Properties

customLabels?

optional customLabels?: string[]

Custom text label per data point, replacing the auto-generated value label. Index aligns with values[]. Empty string or missing entries fall back to the chart-level label settings. Supported for BAR, LINE, AREA, RADAR, PIE, and DOUGHNUT chart types.

Example

['Low', '', 'High']  // only points 0 and 2 get custom labels

---

errorBars?

optional errorBars?: ChartErrorBarOptions | ChartErrorBarOptions[]

Error bars for this series (<c:errBars>).

• Supported for BAR, BAR3D, LINE, AREA, and SCATTER chart types (RADAR has no error bars in the schema).
• Pass a single config, or an array to draw both X and Y error bars (SCATTER/AREA only; BAR/LINE use the first entry).

Examples

{ valueType: 'percentage', value: 5 } // ±5% error bars

{ valueType: 'fixedVal', value: 2, barType: 'plus', noEndCap: true }

{ valueType: 'cust', plusValues: [1, 2, 1], minusValues: [0.5, 1, 0.5] }

---

labels?

optional labels?: string[] | string[][]

category labels

Examples

['Year 2000', 'Year 2010', 'Year 2020'] // single-level category axes labels

pointStyles?

optional pointStyles?: ChartDataPointStyle[]

Per-data-point visual overrides (border / fill), index-aligned with values[]. Empty ({}) or missing entries fall back to series/chart styling. Supported for BAR, LINE, AREA, SCATTER, PIE, and DOUGHNUT chart types.

Example

pointStyles: [
  { border: { width: 2, color: 'FF0000' } }, // point 0: red 2pt border
  {},                                     // point 1: default
  { fill: '00B050', border: { type: 'dash', color: '404040' } }, // point 2
