Area Chart in Vue Component

15 Dec 202424 minutes to read

Area

To render an area 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 Area in your chart configuration. This indicates that the data should be represented as an area chart, which is ideal for showing trends over time or across categories, with filled areas beneath the lines representing data points.

• Inject the AreaSeries module: Use the provide: { chart: [AreaSeries]} method to inject the AreaSeries module into your chart. This step is essential, as it ensures that the necessary functionalities for rendering area 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.

Series customization

The following properties can be used to customize the area series.

Fill

The fill property determines the color applied to the series.

The fill property can be used to apply a gradient color to the area series. By configuring this property with gradient values, you can create a visually appealing effect in which the color transitions smoothly from one shade to another.

Multicolored area

To render a multicolored area 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 MultiColoredArea in your chart configuration. This specifies that the series should be rendered as a multicolored area chart, with different segments of the area having distinct colors.

• Inject the MultiColoredAreaSeries module: Use the provide: { chart: [MultiColoredAreaSeries]} method to inject the MultiColoredAreaSeries module into your chart. This step is essential, as it ensures that the necessary functionalities for rendering area series are available.

• Customize the Segments: Define the segments of the series using the segments property. Each segment can be customized with properties such as value, color, and dashArray.

  • value - Specifies the endpoint of the segment.
  • color - Defines the color of the segment.
  • dashArray - Defines the dashes or gaps in the segment.
