Currently facet axis labels do not support the few formatting tags recognized by other labels in the charts (<b>
, <i>
and <br>
). This is so because of the algorithm that draws text ellipsis (...
) if the label does not fit.
I added a very small fix for the next 1.12.2 release (planning to release it later today) that will remove these known formatting tags and decode HTML entities for these labels so that even if the bold and italic will not be rendered, the label otherwise would be correct.
