Hi,

Do you mean curved text? If so there is nothing build into Bokeh for that. Perhaps you could write a custom extension to accomplish it somehow. Otherwise if you just mean standard labels, I think you will be stuck computing the label positions yourself at the moment. Point/marker-like glyphs work well with LabelSet described here:

  https://bokeh.pydata.org/en/latest/docs/user_guide/annotations.html#labels

But wedges don't have any coordinates for LabelSet to use, except the center x,y positions, which is not useful in this case. There have been vague discussions in the past of adding some notion of "anchor points" to glyphs so that the glyphs could define good points to attach labels, etc themselves, but nothing yet has ever come of that. Please feel free to make an issue on GitHub for new feature development.

Thanks,

Bryan
