You can change duration of the internal indicator’s animation using the Duration
property of the indicator. It should be less then interval between arriving of 2 indicator values.
We are currently researching the new feature which will allow setting indicator value using sequential list of values using the so called “refresh rate”. If there are several updates per second, it becomes difficult to read the values as they flash by. Increasing the refresh rate will restrict the number of display updates, thus giving the user a chance to read the values as they change.
