I have a line graph of temperature with a value every 5 minutes. I need to insert an icon at the top of the graph every 60 minutes according to the temperature values. The icons will be: freezing, cold, warm, the warmest.
The data is inserted into series -> data:
data: [[1679330100000,-11.9],[1679330400000,2.2],[1679330700000,2.2],[1679331000000,4.1] ......
Can you advise me please?
