show_blank_data doesnt work with filter_period

            'show_blank_data' => true,
            'filter_days' => 7,

This seems to fill in the data gaps

However the below will not, but probably could

            'show_blank_data' => true,
            'filter_period' => 'week',

@addshore perhaps you're right. But at the moment we don't have time to work on this particular package, so you could submit a PR if you're deep enough in the package so you would find a quick fix.

Thanks!
