Exported chart is shrunk in 0.4.5

[actionbrk]

🐛 Bug Report

Exported chart looks different between 0.4.4 and 0.4.5. It looks shrunk in 0.4.5.

🔬 How To Reproduce

Steps to reproduce the behavior:

1. Install datawrapper v0.4.4.
2. Execute code sample and see exported chart.
3. Install update to v0.4.5 (it only updates the datawrapper package).
4. Execute code sample again and see exported chart.

Code sample

dw = Datawrapper(access_token=token)
df = pandas.DataFrame(
    [("01/01/2020", 2), ("01/02/2020", 4)], columns=["date", "messages"]
)
chart = dw.create_chart(title="Shrunk", chart_type="column-chart", data=df)
dw.export_chart(chart_id, filepath=f"{chart["id"]}.png")

Environment

• OS: Windows 10
• Python 3.8.3

Screenshots

📈 Expected behavior

Exported chart should not look shrunk.

Hi @actionbrk , would you mind sharing both versions of the chart? Shrunk and non-shrunk?

I just tried recreating it and I get the same chart for both 0.4.4 and 0.4.5

Hi @chekos,

I recreated a new venv (still in Python 3.8.3) and pip installed datawrapper (v0.4.4), pandas and python-dotenv. I ran the same code. As with my old venv, the chart looks nice in 0.4.4 :

Then I updated datawrapper with pip install -U datawrapper. Not much new packages were installed :

Successfully installed commonmark-0.9.1 datawrapper-0.4.5 rich-9.13.0 shellingham-1.4.0 typer-0.3.2 typing-extensions-3.7.4.3

I ran the code again and got a shrunk chart :

I first thought I had a problem with dependencies. I pip uninstall datawrapper and pip install datawrapper==0.4.4 and ran the code again to make sure the new dependencies coming along with 0.4.5 are not the problem ; but going back from 0.4.5 to 0.4.4 fixes it.

Here are the installed packages I have (pip freeze) :

backcall==0.2.0
certifi==2020.12.5
chardet==4.0.0
click==7.1.2
colorama==0.4.4

parso==0.8.2
pickleshare==0.7.5
prompt-toolkit==3.0.18
Pygments==2.8.1
python-dateutil==2.8.1
python-dotenv==0.17.0
pytz==2021.1
requests==2.25.1
rich==9.13.0

six==1.15.0
traitlets==5.0.5
typer==0.3.2
typing-extensions==3.7.4.3
urllib3==1.26.4
wcwidth==0.2.5

Maybe the Python version has something to do with it? I think I will try to do the same with Python 3.9.

I created a new venv with Python 3.9.4. I went through the same steps and I ended up with the same problem (and same dependency list).

Sorry for the delay in response! i'm taking a look at this today. In datawrapper 0.4.5 we changed the default width to 100 (and the unit is still defaulted to "px") whereas before it was set to 600. That was a mistake on our part! Thanks for catching it @actionbrk

This will be fixed in 0.4.6 but in the mean time you can just dw.export_chart(chart_info['id'], title = "cool chart", width = 600) to restore previous behavior (or change it to whatever works for you!)

Again, thanks for catching this AND letting me know, I hadn't heard from other users but this is not the behavior I want by default 🚀
