Graphs are often used in scientific literature because it can directly show the relationship between two quantities, and more important information more easily captured visually from the graph and the data listed in table form. Besides the role as the above graph, the graph also has a role in analyzing data and testing the model at the time of execution of the experiment.
The graphics are most often used is a Cartesian graph, which has an axis perpendicular to the cross, and fixed or linear scales on each axis. The simplest is a coordinate system in which both axes using the same scale and this is often used by people to draw a mathematical formulas. However, in most applications experimentally, the two quantities are about to be drawn in graphical form different from each other and the scale also have different things. A pair of data, such as Xo and Yo, respectively, can be placed on the graph area in accordance with the scale for x and y axis respectively.
In addition to Cartesian graph, some form of graphs that are commonly used in certain situations are polar graphs, and charts logarithmic graph consisting of log-linear (semi log) and log-log graph. In all types of graphs mentioned above, every point in the graph represents a particular data set, and vice verse. The histogram is a kind of graph that is often used in statistical analysis. Histogram showing the number of members or events that fall between certain values in the observable quantities. Need we know that basically the graph shows the relationship between two quantities, but the effects of other values which can be shown by putting a few curves, namely the value of the third scale different. But this way there is no scale for the magnitude of the third. Another way is to use three-dimensional graph that resembles the map arise, but the paint is very difficult and usually done with a special graphics program on the computer.
