elukey edited a comment on issue #7006: World map viz not working in 0.29rc7/0.31.0rc18 URL: https://github.com/apache/incubator-superset/issues/7006#issuecomment-476680851 @mistercrunch would something like this work for you? ``` # df[metric] will be a DataFrame # because there are duplicate column names - ndf['m1'] = df[metric].iloc[:, 0] + if isinstance(df[metric], pd.DataFrame): + ndf['m1'] = df[metric].iloc[:, 0] + else: + ndf['m1'] = df[metric] ``` Given what written in the comment I suppose that the original code was a workaround for a specific Pandas behavior, that seems to have changed. In theory the above code should be good for all pandas versions.
