    Hi Telerik, 


    We are having some difficulty using a RadVerticalLinearGuage. Within a VerticalLinearScale, we are binding the Min and Max properties to ViewModel properties called UpperBound and LowerBound. Most of the time, when these values are updated in the viewmodel, the Marker we are using to position at a "current value" gets drawn in our UI correctly. Occasionally, however, these appear to not be updated, and the chart marker that points to the current value of the series ends up flying way outside the range. Is Telerik aware of any silent errors or race conditions associated with updating of the min and max range of our chart. I am wondering if there is a requirement to update the range before the property that is bound to the Value of the Marker. Your help is much appreciated.

    Hello Stephen,

    Thank you for the provided information.

    Currently, we are not aware of the behavior that is described. I am afraid that I cannot say what is the reason for it without being able to reproduce it on my end.

    May I ask you to provide some more information about the scenario? Can you share some sample code of the gauge/viewmodel? Can you also share what steps are performed before the undesired behavior is reproduced? Sharing a sample video will also be helpful. This way I will hopefully be able to reproduce the result on my end and better assist you.

    Thank you in advance for any help you can provide.
