I could not find a way to make Zorro plot only one hour from a certain day, for example from 10am to 11am. (As far as I have seen, as of now plots always start at 0am on a specific date and there is no way to move the beginning to a later hour.)
Plotting a single hour would zoom in on what happens there and actually display candles instead of a price line.
Any plans to implement this in the future? Or maybe there is a way to do this already after all?

Maybe, add the hours before the plot starts to the LookBack?

How would you do that? Could you give a code snippet?

This would not work since the lookback period is subtracted when you plot at a certain date. At the moment, there is indeed no variable for starting at a certain hour. This will be solved with the upcoming interactive chart viewer where you can zoom in at any chart position.

Wow, eagerly awaiting the interactive chart viewer!
Any deadlines on it known?
