Make it so daily graphs can show 'Day of the Week' so we can track our spending habits better.

When I'm looking at the graphs with daily data, I cant tell which day of the week it was even from the hover over.

As a user I want to be able to review my historic spending and be able to tell what day of the week I spent money on (ie for a specific tag) so that I can keep track of my spending habits and realise things such as, Oh that midweek Groceries stockup is really taking a toll it's cheaper when I do one good shop a week, that sort of thing.

In all graphs reporting daily data, please include Day of the week' in the hover over data.
(Example: My Accounts tab, view 1 month, hover over a date, no day of week currently)
