Bar chart with hours and mins

Hello I have created a helper that shows how long I was not in home.
1)It shows minutes, and it resets every day (at midnight).
2)I have got also another helper that converts minutes to more human friendly format like hh:mm

so 28AUG i was 439min away form home, and at 29AUG i was 400mins away form home.Look at Pic1

I d like to create a bar graph, with 7 days, and it will shows how long i was not @ home.

When I use history graph it shows what I want, but I d like to have on BAR graph, with 7 days.
Look at Pic2

So i d like to have something like that: (but with 7 days)
Look at Pic3
How to do that?
