Disadvantage: depending on the scale/intervals it may be difficult to identify the exact number of data
Double bar graph advantage: best for comparing two sets of data across categories

How can graphs be misleading. Show 3 ways.
1.Distorting the scale(putting a break on y-axis)
2.Distorting the visuals(make the symbol larger than the rest)
3.distorting the size of the bars(make 1 bar wider or put area)
