What a line graph is:
A line graph displays data that continuously changes over a period of time. It can be obtained from bar graphs and histograms ( every histogram is a bar graph ) by joining the mid-point of the top edges of every bar. This makes the analysis easier.
If you look in economic terms ( shown in picture ) everybody uses line graphs from small business owners to the president.
