Pareto Chart in Vue Component

14 Oct 202424 minutes to read

Pareto

Pareto charts are used to find the cumulative values of data in different categories. It is a combination of Column and Line series, where the initial values are represented by the column chart and the cumulative values are represented by the line chart.

To render a pareto series in your chart, you need to follow a few steps to configure it correctly. Here’s a concise guide on how to do this:

• Set the series type: Define the series type as Pareto in your chart configuration. This indicates that the data should be represented as a pareto chart, will use a combination of column and line series.

• Inject the necessary modules: Use the provide: { chart: [ParetoSeries, ColumnSeries, LineSeries]} method to inject the ParetoSeries, ColumnSeries, LineSeries modules into your chart. This step is essential, as it ensures that the necessary functionalities for rendering pareto series are available in your chart.

Binding data with series

You can bind data to the chart using the dataSource property within the series configuration. This allows you to connect a JSON dataset or remote data to your chart. To display the data correctly, map the fields from the data to the chart series xName and yName properties.

Pareto customization

Fill

Use the fill property to apply a color to the pareto line. By default, a color based on the theme is used.
