Yes, it would be helpful to be able to visualize values in their proper form. One use case for the generic I2C driver is a developer writing a quick driver and a user monitoring the output.

However, if it's only a question of scaling, this could be done inside the scopes plugin. There's already a couple math functions, including scaling by 10^1/10^-1. This order of magnitude scaling could be extended to support arbitrary scaling.

I'd prefer to do the scaling on-board, as at the low data rates it's not much of an impact on CPU, but wouldn't be against doing it in the GCS.
