Arc Gauge Scale

The scale of the arc gauge renders the values, pointers and labels. You can customize it by adding an instance of the <ArcGaugeScale> to the <ArcGaugeScales> collection, child tag of the <TelerikArcGauge>. The <ArcGaugeScale> exposes the following parameters:

Min and Max

  • The Max (double) parameter controls the maximum value that the component can reach.

  • The Min (double) parameter controls the lowest value of the component.

Change the lowest and the highest values for the scale. The result from the code snippet below.

Min and max parameters example

@* Use the Min and Max parameters to change the lowest and highest values for the scale *@

<TelerikArcGauge>
    <ArcGaugeScales>
        <ArcGaugeScale Min="10" Max="100">
            <ArcGaugeScaleLabels Visible="true" />
        </ArcGaugeScale>
    </ArcGaugeScales>

    <ArcGaugePointers>

        <ArcGaugePointer Value="30">
        </ArcGaugePointer>

    </ArcGaugePointers>
</TelerikArcGauge>

MinorUnit and MajorUnit

  • The MajorUnit (double) parameter controls the interval between the major unit divisions of the component. The values provided to the ArcGaugePointer will render as a MajorUnit tick. The labels will be rendered next to the MajorUnit ticks.

  • The MinorUnit (double) parameter controls the interval between the minor unit divisions of the component. In order to use the MinorUnit ticks you must enable them explicitly.

Change the rendering frequency of the major unit divisions. The result from the code snippet below.

Minor and major units parameters

@* Update the rendering of the major ticks *@

<TelerikArcGauge>
    <ArcGaugeScales>
        <ArcGaugeScale Min="0" Max="100" MajorUnit="10">
            <ArcGaugeScaleLabels Visible="true" />
        </ArcGaugeScale>
    </ArcGaugeScales>

    <ArcGaugePointers>

        <ArcGaugePointer Value="30">
        </ArcGaugePointer>

    </ArcGaugePointers>
</TelerikArcGauge>

StartAngle and EndAngle

  • The StartAngle (double) parameter controls the starting angle of the scale.

  • The EndAngle (double) parameter controls the ending angle of the component.

By default the StartAngle is set to 0 and the EndAngle to 180. These values represent the angles on the coordinate system.

Change the StartAngle and the EndAngle of the scale. The result from the code snippet below.

Min and max parameters example

@* Use the StartAngle and EndAngle parameters to curve the scale differently. *@

<TelerikArcGauge>
    <ArcGaugeScales>
        <ArcGaugeScale Min="0" Max="100" StartAngle="-45" EndAngle="180">
            <ArcGaugeScaleLabels Visible="true" />
        </ArcGaugeScale>
    </ArcGaugeScales>

    <ArcGaugePointers>

        <ArcGaugePointer Value="30">
        </ArcGaugePointer>

    </ArcGaugePointers>
</TelerikArcGauge>

Reverse

If you set the Reverse (bool) parameter to true the values of the scale will increase from the right side to the left side of the scale. By default they will raise from the left to right.

Reverse the scale of the component. The result from the code snippet below.

reverse parameter example

@* Set the Reverse parameter to true *@

<TelerikArcGauge>
    <ArcGaugeScales>
        <ArcGaugeScale Min="0" Max="100" Reverse="true">
            <ArcGaugeScaleLabels Visible="true" />
        </ArcGaugeScale>
    </ArcGaugeScales>

    <ArcGaugePointers>

        <ArcGaugePointer Value="30">
        </ArcGaugePointer>

    </ArcGaugePointers>
</TelerikArcGauge>

Additional Customization

Example: Enable the MinorUnit ticks

You can enable the MinorUnit ticks on the scale by using the <ArcGaugeScaleMinorTicks> nested tag and its Visible parameter.

Add the MinorUnit ticks to the scale. The result from the code snippet below.

Add the MinorUnit ticks

@* Add the MinorUnit ticks. *@

<TelerikArcGauge>
    <ArcGaugeScales>
        <ArcGaugeScale Min="0" Max="100" MajorUnit="20" MinorUnit="5">
            <ArcGaugeScaleMinorTicks Visible="true" />
            <ArcGaugeScaleLabels Visible="true" />
        </ArcGaugeScale>
    </ArcGaugeScales>

    <ArcGaugePointers>

        <ArcGaugePointer Value="30">
        </ArcGaugePointer>

    </ArcGaugePointers>
</TelerikArcGauge>
