Characters in plot title are not bottom-aligned (not sitting on same baseline)? #1010
Description
I ran into this a month ago via a work project, then went to reproduce but doubted myself. It looked to me like text was not aligned across the baseline. At the time, I think I was making some plots including a "$" in the axis labels or title, and convinced myself it was the inclusion of a symbol, which I accept might affect the overall line typesetting.
I ran into it again just now, and was able to make an example that shows what I mean:
import pandas as pd
from plotnine import *
df = pd.DataFrame({'x': [0, 1, 2], 'y': [3, 4, 5]})
p = ggplot(df, aes(x='x', y='y')) + geom_point()
p = p + theme_bw(base_size=14) + ggtitle('ABCs')
p
This is in jupyterlab, not sure if that affects things? I used right click > copy cell output to paste into powerpoint so I could crop and zoom in, and then added this red line.
I also changed base_size to 32 and then used p.save() to png and it does still look present (so not just a jupyterlab artifact):
I wondered if it was matplotlib, so I tried an equivalent plot there, but it looks more aligned.
import matplotlib.pyplot as plt
plt.plot([1, 2, 3], [4, 5, 6])
plt.title("ABCs", fontsize=32)
plt.show()
Pasting and cropping, it's slightly there with the C and s a bit closer to the line, but not as exaggerated as via plotnine.
Let me know if there's anything I can help look into or reproduce!
