Wireshark isn't really the tool for this, it's a packet analyzer not a network monitor. You could capture with Wireshark using a capture filter to limit the traffic to that created by your application and then post-process the resulting capture file using a programming language with pcap support to separate the traffic into 1ms blocks and then calculate the total traffic received in each block.
You might struggle to find any existing tool that can determine the bandwidth over such a small period of 1ms.
