What type of graph can show data over time ?
Bar
Line
Pie
What type of graph shows proportions of a whole eg shows percentages ?
Which type of graph compares data across a range of categories ?
If I had data to show the increase in iPhone sales over 10 years i would choose a bar chart
If I had data about the proportion of votes for each party in the election I would use a pie chart
If I was graphing the amounts of people watching Guardians of the Galaxy at 4 different cinemas I would use a line graph
