Lovelace: mini graph card

Good evening,
I have a problem with an implementation,
I want to record the uptime in hours and minutes of a computer per day.
I use a binary_sensor.chris_pc with Ping (ICMP) integration,
On this, I record when the computer is connected,
I have done this:

    name: Chris PC Daily Uptime
    entity_id: binary_sensor.chris_pc
    state: 'on'
    type: time
    start: '{{ now().replace(hour=0, minute=0, second=0) }}'
    end: '{{ now() }}'

to measure the hours, and then I placed it on the card like this:

But I see that it records it wrong. What I want, I think, is simple,
I want to measure the usage per day to know how many hours the computer was on per day, can it be done?

Hi, Is there any way to get a action to happen when i click on the actual graph ?
It works clicking on any of the text or icon. but would like it to also work on the graph as I like the clean no points no label look.
want to go to more-info when i click the graph.

How to add different icons to displayed states of entities (marked as red 1 and 2)?

My graph is generally connected to first entity and Iā€™d like to add only numeric value of second one and mark both by icons showing what is there. I tried to look for solution by own, but this thread is too big, sorry.
