Here are some bar plots with complex questions can be answered by decomposing into several extractive questions. In the bar plot, each category has its corresponding value. 

Bar plot of: [“twitter”, “YouTube”, “WeChat”, “Spotify”, “CNN”]. 

Question: what is the sum of “WeChat” and “Twitter”? 
Answer: ans=ans_1+ans_2
ans_1=what is the value of “WeChat”? 
ans_2=what is the value of “Twitter”?

Question: what is the NAME_1 value of “WeChat”, “Spotify” and “Twitter”? 
Answer: ans=NAME_1(ans_1, ans_2, ans_3)
ans_1=what is the value of “WeChat”? 
ans_2=what is the value of “Spotify”?
ans_3=what is the value of “Twitter”?

Line plot of: [“2013”, “2014”, “2015”, “2016”, “2017”, “2018”]

Question: what is the min value of all the years?
Answer: ans=min(ans_1, ans_2, ans_3, ans_4, ans_5, ans_6)
ans_1=what is the value of “2013”?
