The bit-loading graph looks right, but I'm not sure about the SNR graph.
SNR should look similar to bit-loading, but slightly less "blocky".
Also, SNR's maximum value should be around 50dB to 60dB.
It looks like you have divided the Hex value A5 (165 dec) by 10 to give 16.5, so something doesn't look quite right there.
I have no idea what gain is.
I have attached a set of graphs from a HG612 modem on an ECI DSLAM (so it shows the ECI's tone band plans rather than the usual HG612's tone band plans).
Yes, apart from bit-loading, the graphs show DS only data.
The example doesn't show anything of the D3 tone band plan, as attenuation is too high to actually use any of it at Medley Phase, but it was discovered at Discovery Phase.
