Calculating sum of daily data in ThingSpeak

Hello everyone.

I am sending data from liquid sensor to my ThingSpeak Channel. The data is updated every 20 seconds. I want to visualize daily and hourly total liquid. How can I do that? Possibly in MATLAB visualizations in ThingSpeak? I have attached a picture of the graph in my ThingSpeak channel.

I look forward to hearing from you soon.

Best Regards
Rushan
