A little help with mini-graph-card please

Hi all,

i'm trying to lift my terrible admin-style dashboard out of the bin and have been playing with the mini-graph-card, first stop was my climate.

The original was this....

And was trying the MGC and reached here...

But its not really doing much for me so far. I like the history graph but think the min/max (both entities) are poor?

Current code is this...

type: custom:mini-graph-card
name: CLIMATE
icon: mdi:temperature-celsius
entities:
  - entity: sensor.hue_current
    name: Current
  - entity: sensor.hue_max
    name: Max
    color: "#f44336"
  - entity: sensor.hue_min
    name: Min
    color: "#2196f3"
align_state: center
extrema: true
show:
  fill: false
color_thresholds:
  - value: 0
    color: "#05a4eb"
  - value: 12
    color: "#ebbd05"
  - value: 18
    color: "#faa369"
  - value: 23
    color: "#ff9800"
  - value: 28
    color: "#f44336"

Can anyone throw in some tips on a decent climate display if possible ?

Many thanks
