### What you expected to happen
For the task to complete (since it runs fine locally in a jupyter notebook
running on the same software env) and for the figure to be plotted and stored
locally.
### How to reproduce
Reproduce with this DAG:
```python
from datetime import datetime, timedelta
import matplotlib.pyplot as plt
import numpy as np
from airflow.decorators import dag, task
# set default arguments to all tasks
default_args = {
'owner': 'rrpelgrim',
'depends_on_past': False,
'email_on_failure': False,
'email_on_retry': False,
'retries': 3,
'retry_delay': timedelta(minutes=5),
}
@dag(
default_args=default_args,
schedule_interval=None,
start_date=datetime(2021, 1, 1),
catchup=False,
)
def dag_name():
@task()
def visualize():
"""
Create visualisation plots and save as PNGs.
"""
# Create boxplot
data = np.arange(1,20)
fig, ax = plt.subplots(figsize=(10,10))
plt.title('Title', fontsize=15)
plt.boxplot(x=data)
plt.savefig('boxplot_test.png')
plt.close(fig)
print('Visualisations have been created.')
# Call task functions in order
viz = visualize()
# Call taskflow
demo = airflow_on_coiled_testing()
```
