TPS graph for SMPP traffic from Wireshark capture

Hello,

Looking for some help on how to draw a throughput graph for SMPP traffic from the Wireshark capture. I am able to produce a nice graph from the I/O Graphs under statistics but the problem I am facing is, I have multiple SMPP submit_sm PDUs under a single frame and the I/O graph is not considering the multiple PDUs instead it is taking it as a single PDU. It would be grateful if someone can help me out in drawing a graph.

Best Regards, Prakash Galla
