Hello,

I`m try to use two needle in gauge to make a style like a clock but when I add second needle with relativewidth equal 0.1 this needle don`t change width, but if I use relativeheight the needle change height.

Thank You!

Hi Alexandre,

You can find clock style radial gauge example in the Time Monitor example. The RelativeWidth have no effect for the needle indicator. Width of the needle is controlled by its Location and Offset properties (see "Time Monitor" example).

Kind regards,

Im also having trouble with getting a needle to be sized properly but I didnt want to start a new thread on the same issue.

The code from the example only shows the use of "Offset" being used, but it doesnt seem to do anything on mine, any help?

Im making a clock, so there are 3 needles on the page and so I would like them to be different sizes

Page code:

 
        <StackPanel x:Name="uxClockPanel">  
            <control:RadGauge x:Name="uxClockGauge" Width="600" Height="600" Visibility="Collapsed">

Hello Stephen,

This is the expected behavior. When you don't specify Location property for the Needle indicator it uses the OverCenter value by default. This value specifies that arrow of needle must be positioned at the center of the radial scale. The Offset value has no effect in this case, because there is no direction to offset arrow to for this location.
To be able offset needle you have to choose one of the locations which specify direction of offset: Outside, OverOutside, OverInside, CenterInside, CenterOutside, or Inside.
For example:
<gauge:Needle x:Name="uxClockNeedleMinute" IsAnimated="True" Location="CenterInside" Offset="0.3" Value="10" />
<gauge:Needle x:Name="uxClockNeedleSecond" IsAnimated="True" Location="CenterInside" Offset="0.1" Value="15">
