Step area Chart in Vue Component
15 Dec 202424 minutes to read
Step area
To render a step 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
typeasStepAreain your chart configuration. This indicates that the data should be represented as a step area chart, which connects data points with vertical and horizontal lines, creating a step like appearance. -
Inject the StepAreaSeries module: Use the
provide: { chart: [StepAreaSeries]}method to inject theStepAreaSeriesmodule into your chart. This step is essential, as it ensures that the necessary functionalities for rendering step area series are available in your chart.

</style>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.
