im new to HA and struggling to get my head around everything. How to make the bar colors change based on the values? I want the NordPool electricity price data chart to show the high price bars red, middle orange, low green etc, but I want them to be set depending on the max price of the particular day, lets say, the max shown price of the cart today is 50 EUR, so the 80%-100% of the max price will show up red, 60%-80% orange etc. Currently I have them set as 0-10 EUR = blue 10-20 green etc. But that's not convenient if all the hourly prices of the day are, lets say in a range of 0-10 - then all the bars are shown in blue.
