Mini Graph Card - Show total instead of 'per day'

So I am using mini-graph to showcase daily costs for the past 7 days, and its working great, when I hover over each date it reads each cost correctly.

Am I able to display the sum of these daily costs by default in the graph, instead of reading today’s cost?

For example instead of showing 3.65, it would total the days up to around £25 and show this figure.
