Spline Chart in Vue Component
14 Oct 202424 minutes to read
Spline
To render a spline 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
typeasSplinein your chart configuration. This indicates that the series should be represented as a smooth curve, connecting data points with a spline rather than straight lines. -
Inject the SplineSeries module: Use the
provide: { chart: [SplineSeries]}method to inject theSplineSeriesmodule into your chart. This step is essential, as it ensures that the necessary functionalities for rendering spline series are available in your chart.

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.
