Drawing peak meters in my plugin

Question

The Wwise documentation is fairly clear how to send data from an engine plugin to a Wwise plugin via AK::Wwise::IAudioPlugin::NotifyMonitorData, and it demonstrates how to make custom controls in text boxes, but I find nothing on how to actually draw them. If I have to do crazy MFC weirdness I will not be very excited, so I'm hoping Wwise has something built-in. For example, the McDSP limiter plugin seems to have meters that look identical to the meters in the Wwise application, so is there not some unifying interface for this?
