graph definition

In general terms, the word graphic refers to writing or printing and everything related to them.

But also, by graph, it is understood the representation of data, almost always numerical, although they can also be figures or signs, through lines, surfaces or symbols to determine the relationship that they maintain with each other.

Meanwhile, it may be that it is a set of points, which will be reflected in Cartesian coordinates and that will serve to analyze the behavior of a certain process or a set of signs or elements that allow us to decipher or interpret some phenomenon, among other issues. .

We can find different types of graphs, among the most common and common are: numerical ones, used to represent the behavior or distribution of quantitative data in a population. This type of graphic is manifested through visual images. On the other hand, the linear ones will represent the values ​​in two orthogonal Cartesian axes to each other. More than anything, this type of graph is recommended when having to represent series over time, because it allows to show maximum and minimum values ​​of a question.

Another type are bar graphs, which will be used when you want to highlight the representation of percentages that refer to a total. The bars that allow is the representation of frequencies and can be plotted horizontally or vertically, generally, to represent the bar graphs, so-called spreadsheets are used.

Then there are the circular graphs that will allow us to observe those internal distributions of data that represent a fact, also in the form of percentages over a total. According to the interest of what you want to highlight, what you do is separate the sector corresponding to the highest or lowest value. And finally, histograms, another type of very common graph, which will be used when you want to represent samples grouped in intervals. It is formed by rectangles joined to each other, whose vertices of the base must coincide with the limits of the intervals.

On the other hand, the word graphic is also used to refer when in a certain situation you want to realize that someone expresses himself with great clarity, almost with the same clarity as a drawing.
