Given a graph G, its line graph L G is a graph such that each vertex of L G represents an edge of G; and two vertices of L G are adjacent if and only if their corresponding edges share a common endpoint "are incident" in G. That is, it is the intersection graph of the edges of G, representing each edge by the set of its two endpoints. Each vertex of the line graph is shown labeled with the pair of endpoints of the corresponding edge in the original graph.
An efficient way to present data Why use a line graph? Of all the visuals in Excel, why choose a line chart? Plenty of other charts show the same information, so why not use them? Here are a few significant advantages of line graphs: They show things over time very well.
On a line graph, people will see this very quickly. There are other good uses for line charts, but showing a value over time is one of the best.
They make it easy to see multiple sets of data. Clustered and stacked charts let you show a lot of data in a small space, but they can Line graph difficult to read. Using different-colored lines in a line graph is much clearer. You can even show interactions between values with this chart, which is great for complicated datasets.
Line charts are simple. In fact, in their most basic form, they only contain one thing: Additional information is easy to see. Error bars, data labels, trend lines, and other useful statistical notations are very clear on line graphs.
Line charts solve that problem by leaving a lot of white space for you to work with. Kasper Langmann, Co-founder of Spreadsheeto However, there are a few cases in which you might not want to use a line graph.
Put each category and the associated value on one line: You could also put them in separate rows instead. Both work equally well.

More than that makes your graph much harder to read. How to make a line chart Once your data is properly formatted, you can create your chart.
It only takes a few clicks. If you forget which button to click, just hover over the options. Excel will tell you which one is which. When you click that, your line graph will appear! The easiest way to do this is with chart styles.
Mouse over them to see a preview: Clicking any of these styles will immediately format your chart. Different styles include a variety of chart elements.
Excel automatically calculates the standard error or whatever is necessary for your chosen element and inserts it into the graph. Keep in mind that you can also remove elements through this menu, as well. Kasper Langmann, Co-founder of Spreadsheeto Data tables, grid lines, trend lines, axis labels, and more can be found in this menu.(Notice that the slope goes uphill and is a positive number) For, you can "rise" up or down but, you ALWAYS "run" to the right..

The line. What is a Line Graph? A line graph, also known as a line chart, is a type of chart used to visualize the value of something over time. For example, a finance department may plot the change in the amount of cash the company has on hand over time.
Formal definition. Given a graph G, its line graph L(G) is a graph such that. each vertex of L(G) represents an edge of G; and; two vertices of L(G) are adjacent if and only if their corresponding edges share a common endpoint ("are incident") in G.; That is, it is the intersection graph of the edges of G, representing each edge by the set of its two .
