Adding a RadRadialGauge to your page

First thing you need to do before adding the RadRadialGauge to the page is to define its namespace:


Before adding RadGauge for NativeScript, make sure you have installed Progress NativeScript UI Pro.

Here's how to add a RadGauge instance to your page:

Example 1: Add a RadRadialGauge to your page.


Adding scale with indicators

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.

Example 2: Add a scale with indicators to the gauge.


    <gauge:RadialScale minimum="0" maximum="6" radius="0.90">
            <gauge:ScaleStyle majorTicksCount="7" minorTicksCount="9" lineThickness="0" labelsCount="7" ticksOffset="0"/>

            <gauge:RadialBarIndicator minimum="0" maximum="1.2" location="0.97">
                    <gauge:BarIndicatorStyle fillColor="#dddddd" />

            <gauge:RadialBarIndicator minimum="1.2" maximum="2.4" location="0.97">
                    <gauge:BarIndicatorStyle fillColor="#9DCA56" />

            <gauge:RadialBarIndicator minimum="2.4" maximum="3.6" location="0.97">
                    <gauge:BarIndicatorStyle fillColor="#F0C44D" />

            <gauge:RadialBarIndicator minimum="3.6" maximum="4.8" location="0.97">
                    <gauge:BarIndicatorStyle fillColor="#E27633" />

            <gauge:RadialBarIndicator minimum="4.8" maximum="6" location="0.97">
                    <gauge:BarIndicatorStyle fillColor="#A7010E" />

            <gauge:RadialNeedle value="2" />
