Properties ​

_dataIndex? ​

optional _dataIndex?: number

Defined in: core-interfaces.ts:2004

Inherited from ​

OptsChartData._dataIndex

customLabels? ​

optional customLabels?: string[]

Defined in: core-interfaces.ts:2034

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 ​

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

Inherited from ​

OptsChartData.customLabels

data ​

data: IOptsChartData[]

errorBars? ​

optional errorBars?: ChartErrorBarOptions | ChartErrorBarOptions[]

Defined in: core-interfaces.ts:2057

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 ​

ts
{ valueType: 'percentage', value: 5 } // ±5% error bars
ts
{ valueType: 'fixedVal', value: 2, barType: 'plus', noEndCap: true }
ts
{ valueType: 'cust', plusValues: [1, 2, 1], minusValues: [0.5, 1, 0.5] }

pointStyles? ​

optional pointStyles?: ChartDataPointStyle[]

Example ​

ts
pointStyles: [
  { border: { pt: 2, color: 'FF0000' } }, // point 0: red 2pt border
  {},                                     // point 1: default
