We have written a LUA postdissector that calculates a number of response time
values. These are defined as floating point fields, e.g.
rte_art_F = ProtoField.float("transum.art","APDU Rsp Time")
The postdissector works fine but I can't get the Wireshark IO Graph facility to
plot the values - I just get a flat line. I use the Y Axis Unit: Advanced
option in IO Graph, choose Calc: MAX(*) and then add transum.art as the value
to plot.
I've tried the same thing with Wireshark compiled dissector fields and these
work fine.
Thanks and regards...Paul
