As in, when you run ping with the -D option manually, it gives an error?

yes
ping -D -i 0.20 -w 70 200.200.100.1
.....this one is not running

$ ping -D -i 0.20 -w 70 200.200.100.1
ping: socket: Operation not permitted
...................................... some times i am getting but not often
..in ping -D option is not present

Well, unfortunately having a timestamp on the output of 'ping' (which is
what the -D option does) is required for netperf-wrapper to parse it. If
that's not included in cygwin, you have a couple of options:

1. Add it; i.e. pick up the source code to the cygwin implementation of
   'ping' and make it output UNIX timestamps in front of its output when
   run with -D (or some other parameter if -D is used for something else).
2. Find a different implementation of ping that does have it. fping is
   one such implementation that will work, so getting that to run on cygwin
   might be an option. Alternatively, if you find a different
   implementation that works on cygwin, and also runs on Linux, I'll be
   happy to incorporate a parser for that into netperf-wrapper.
3. Use the UDP ping implementation in netperf instead. The rrul test in
   netperf-wrapper uses this along with a regular ping. However, the
   UDP-based ping has the drawback that it stops pinging on packet loss,
   which depending on your setup may make it unviable.

in Tcp test also i am not getting ping data in graph

The TCP test does not have the UDP-based roundtrip measurement, so
you'll need a working ping command to run that.
