100% Stacked line Chart in Vue Component

14 Oct 202424 minutes to read

100% Stacked line

To render a 100% stacked line 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 StackingLine100 in your chart configuration. This indicates that the data should be represented as a 100% stacked line chart, with each data series shown as a percentage of the total. This chart type ensures that all lines are stacked to always reach 100% at each data point, allowing for easy comparison of the proportional relationships between the series without the influence of absolute values.

  • Inject the StackingLineSeries module: Use the provide: { chart: [StackingLineSeries]} method to inject the StackingLineSeries module into your chart. This step is essential, as it ensures that the necessary functionalities for rendering 100% stacked line 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.

The fill property can be used to apply a gradient color to the 100% stacked line 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.
