Bar Chart in Vue Component

7 Apr 202524 minutes to read

Bar

To render a bar 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 Bar in your chart configuration. This indicates that the data should be represented as a bar chart, which makes it easy to compare values across categories.

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

Opacity

The opacity property specifies the transparency level of the fill. Adjusting this property allows you to control how opaque or transparent the fill color of the series appears.

Corner radius

The cornerRadius property in the chart series is used to customize the corner radius for bar series. This allows you to create bars with rounded corners, giving your chart a more polished appearance. You can customize each corner of the bars using the topLeft, topRight, bottomLeft, and bottomRight properties.
