Hi, i cant seem to solve this after a week. Any suggestions?

[nicolaskruchten]

Can you provide a sample dataset that causes this issue?

[dominic2017]

Hi nicolas, i tried with http://samplecsvs.s3.amazonaws.com/Sacramentorealestatetransactions.csv

Hi frankquekch,
What is your OS? If you are using Windows, try the following workaround:

import pandas as pd
df = pd.DataFrame([['a', 'aaa'], ['b', 'bbb']], columns=['var1', 'var2'])
df

def pivot_ui(df, **kwargs):
    import pivottablejs
    class _DataFrame(pd.DataFrame):
        def to_csv(self, **kwargs):
            return super().to_csv(**kwargs).replace("\r\n", "\n")
    return pivottablejs.pivot_ui(_DataFrame(df), **kwargs)

pivot_ui(df)

Hope it help.

thanks looks good!

Hi I wondered is there a way to add the % value labels for series onto the charts if doing % of row or columns?

[stefaneidelloth]

I also saw the null values on windows and the workaround of overriding the pivot_ui method worked for me.
Could you please detect the OS and fix the line endings automatically in the code?

[bogus-accnt]

Still not solved, but workaround works!

The pivot_ui function should be adapted to specify newline="\n" (instead of using the default "\r\n" on windows)

def pivot_ui(df, outfile_path = "pivottablejs.html", url="",
    width="100%", height="500", **kwargs):
    with io.open(outfile_path, 'wt', newline="\n", encoding='utf8') as outfile:
        csv = df.to_csv(encoding='utf8')
        if hasattr(csv, 'decode'):
            csv = csv.decode('utf8')
        outfile.write(TEMPLATE %
            dict(csv=csv, kwargs=json.dumps(kwargs)))
    return IFrame(src=url or outfile_path, width=width, height=height)
