Description
Hello Daniel,
Thanks again for your fabulous library. I'm scratching my head on how to add a subpanel for a renko chart. I'm trying to add an indicator in the lower panel (an oscillator). Getting into some non-iterrable item error using the external_axes trick. Some help would be much appreciated.
I'm looking for this end result:
PS: How to control the border width on the boxes please :)

Research direction
Start by reproducing the Renko chart setup using the external_axes entry point and the requested lower-panel oscillator. Compare the result with the linked screenshot, including the non-iterable error and box border-width request. Done means the supported approach for both behaviors is established and documented or implemented.
