Run the following command to add the plugin to your application:

tns plugin add nativescript-ui-gauge

Adding a RadRadialGauge to your Component

Before proceeding, make sure that the nativescript-ui-gauge/vue module is required inside your application. This module handles the registration of the custom directives and elements required by nativescript-vue.

To display data the RadRadialGauge instance is not enough. We should add also add a scale with at least on indicator. In this example we are going to add a RadialScale with several RadialBarIndicator instances and one RadialNeedle. To add a scale to the RadRadialGauge we should use its scales property. Adding indicators to the scale is similar - we are using RadialScale's indicators property.

In order to setup an RadRadialGauge in your application you will need to follow this steps:

  • First start by declaring the <RadRadialGauge></RadRadialGauge> tags
  • The main elements that are visualized by the gauge are its scales, in order to declare multiple scales simply declare the <RadialScale v-tkRadialGaugeScales></RadialScale> and set the v-tkRadialGaugeScales inline directive to it.
