Hello Umer,
I am under the impression that you are looking to prevent animation of the IgxRadialGauge in certain circumstances. If my impression is incorrect, I would request that you please elaborate a bit further on your requirement so I may make a more concrete recommendation, as the following is based on this impression.
If you are looking to shut off animation in the IgxRadialGauge in certain circumstances, I would recommend setting the transitionDuration property to 0. This controls how long the animation takes to finish in milliseconds. If set to 0, the animation will not happen.
Please let me know if you have any other questions or concerns on this matter.
