IEEE 802.11a/g always uses 20MHz channels independent from the modulation and coding scheme. So it will always be a signal with a 20MHz bandwidth.
If you encode data with BPSK and a coding rate of 1/2, the 20MHz signal will carry 6Mbit/s (bits per second, not bandwidth in frequency domain).

If you want to visualize the data throughput, I would recommend to parse the Wireshark output and calculate a moving average. But you won't see the 6 MBit/s. It's only the PHY throughput, which you could only reach if you sent a single frame with infinite size.

Best,
