Getting Started

Getting Started

Chart.js module for charting error bars plots. This plugin extends the several char types (bar, line, scatter, polarArea) with their error bar equivalent (barWithErrorBars, lineWithErrorBars, scatterWithErrorBars, polarAreaWithErrorBars).

Install

npm install chart.js chartjs-chart-error-bars

Usage

see Examples

and CodePen

Configuration

Data Structure

Chart types: bar and line

see TypeScript Interface: IErrorBarXDataPoint

Chart type: bar with indexAxis: 'y'

see IErrorBarYDataPoint

Chart type: scatter

a combination of the previous two ones IErrorBarXDataPoint and IErrorBarYDataPoint

Chart type: polarArea

see IErrorBarRDataPoint

Styling

The styling options support different array version.

Note: as with other chart.js style options, using an array will be one value per dataset. Thus, to specify the values for different error bars, one needs to wrap it in an object with a v key having the value itself. The outer for the dataset, the inner for the error bars.
