[Matplotlib-users] Any way to add figure string for subplots

[vincent.adrien at gmail.com]

Hi Jinbo,

You should be able to achieve this with `annotate`. Here is a small
snippet demonstrating its basic use:
```python
import matplotlib.pyplot as plt
plt.ion()

fig, axs = plt.subplots(ncols=2, nrows=2)  # dummy 2x2 subplot grid

# NB: a better annotation tutorial is available at
# https://matplotlib.org/tutorials/text/annotations.html
for ax, label in zip(axs.flat, ["(a)", "(b)", "(c)", "(d)"]):
    ax.annotate(label,
                (0.02, 0.03), xycoords="axes fraction",  # coordinates
                ha="left", va="bottom",  # horiz. & vertical alignement
                weight="bold", style="italic"  # font option examples
                )
```

If you need to draw a white box behind the annotations, please have a
look at
https://matplotlib.org/tutorials/text/annotations.html#annotating-with-text-with-box

Hopefully this helps.

Best regards,
Adrien
