With a seqspec that has only one modality it seems like the library png plot is too short.

I tried generating some example library structure plots and for the case of a seqspec with only one modality the bar height was flattened. There was also an error message:

~/proj/seqspec/seqspec/seqspec_print.py:94: UserWarning: constrained_layout not applied because axes sizes collapsed to zero.  Try making figure larger or axes decorations smaller.
  s.savefig(o, dpi=300, bbox_inches="tight")

I was using this seqspec https://github.com/detrout/y2ave_seqspecs/blob/main/Team_7_igvf_b01_LeftCortex_13A_seqspec.yaml
with the command:

python3 -m seqspec.main print -o parse-bridge-library.png -f png Team_7_igvf_b01_LeftCortex_13A_seqspec.yaml

and got this plot.

With other libraries that had multiple modalities, the bar height was larger than the region length text.
