They can be very effective if you use them in the right way.
Line graphs are meant for rate that change over time so go with that
Some examples of effective titles for line graphs could be "Trend Analysis of Sales Over Time," "Comparison of Temperature Changes by Month," or "Growth of Population in Urban Areas."
clear presentation of information accurate information simple, meaningful, attractive design
Giving a clear and effective picture. Also referring to the use of diagrams and graphs.
A pie graph is more effective that other types of graphs for showing shares of a total.
Line charts. This is one of my midterm questions for this week hah .
Visual presentation is more effective for many (though not all) people.
Bar graphs are highly effective for showing quantities, as they clearly represent data through the length of bars, allowing for easy comparison between different categories. Pie charts can also depict quantities, particularly when illustrating parts of a whole, but they are less effective for detailed comparisons. Line graphs are useful for showing trends over time but are less effective for displaying discrete quantities. Overall, bar graphs are typically the best choice for directly comparing quantities.
Multivariate is probably the most accurate answers. Graphs need not be bivariate - you can have graphs in 3 or more dimensions - not easy to visualise in more than 3-d but that does not mean they cannot exist. Graphs need not represent exact relationships - as any scattergram will demonstrate. Graphs are simply visual representations of information, presented in a form that [hopefully] conveys he information in an effective way. For one of my favourite semi-numeric graphs follow the link to see a graphical representation of Napoleon's invasion of Rusia.
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
All graphs are graphical graphs because if they were not graphical graphs they would not be graphs!
