The main advantage is that it allows you to see how different dependent variables change according to changes in the same "independent" variable.
It is relatively simple to use two vertical axes for the dependent variables, but the degree to which the two axes relate to one another is arbitrary. Furthermore, if the ranges of the dependent variables are very different the chart becomes unreadable.
Bar graphs are a good way of looking at different kinds of information. They can be a little bit ineffective, though, if you're trying to examine growth over time or things in parts. Pie graphs or line charts can be more effective in those ways.
Easy to compare multiple continuous data sets
line graphs are usually the most best way to present data. sometimes i use pie graphs or bar graphs, but usually line graphs are the most meaningful.

Merits: 1. Its new and its different :) 2. Its more complicated and hence more convincing to people. 3. Its an option anyway Demerits 1. It suks as it is complicated 2. It adds few more pages to your book which makes it costlier and heavier.
One of the merits of power line communication is that it offers great flexibility to where computers and peripherals can be placed. The demerits of power line communication is that if not properly checked it can lead to death especially of children.
Line graphs are most helpful.
Easy to compare multiple continuous data sets
Bar graphs and line graphs do not. Straight line, parabolic, and hyperbolic graphs are graphs of an equation.
circle graphs add up to 100% , bar and line graphs don't
