Hello, how I can disable the crosshairs of Orthoslicer3D?

thank you.

In the short term, you can comment out these lines:

nibabel/nibabel/viewers.py

Lines 501 to 502 in 118d305

	for line in self._crosshairs[ii].values():
	ax.draw_artist(line)

If you'd like to submit a pull request, you could add a _show_crosshairs instance variable that's togglable with a keypress in

nibabel/nibabel/viewers.py

Lines 479 to 492 in 118d305

	def _on_keypress(self, event):
	"""Handle mpl keypress events"""
	if event.key is not None and 'escape' in event.key:
	self.close()
	elif event.key in ["=", '+']:
	# increment volume index
	new_idx = min(self._data_idx[3] + 1, self.n_volumes)
	self._set_volume_index(new_idx, update_slices=True)
	self._draw()
	elif event.key == '-':
	# decrement volume index
	new_idx = max(self._data_idx[3] - 1, 0)
	self._set_volume_index(new_idx, update_slices=True)
	self._draw()

that you could use to selectively deactivate the above lines.

I think freezing some views will require a more significant change. I'm not immediately sure of how I'd go about that.

I know, I'm trying do that, and I've realized that it's not possible show a RGB channel, I'm trying do that too.
