Hi Indranil,
Thanks again for your kind help. I created my JSFiddle and the URL is https://jsfiddle.net/v072b9hz/ .
By the way, I know I shouldn’t set a static array as the data to a responsive chart, but later I’ll change data source to a variable including only one datetime and its corresponding temperature which I’ll get from the server every second. Before that, I just want to make sure everything should work.
