Hi Daniel,
Sorry for the inconvenience.
In our previous update we provided sample in C#. Please find the sample in VB from the following location,
Sample Link : http://www.syncfusion.com/downloads/Support/DirectTrac/General/PulsingDemo557036775.zip
In the above sample we have set PulseDuration as '0:0:3' and PulseScale as'1.5' to achieve your requirement. Can you please clarify whether the sample updated assists to identify the problem in your sample or modify the sample to showcase your problem which will help us to provide accurate solution.
Please let us know if you have any queries.
