The first Weather Bureau Office to open in Arizona was in Yuma where the duties were transferred from the Army at Fort Yuma in July 1891. Tucson followed in September of that year, and it was not until four years later that the small community of Phoenix rated a full station.
Different types of graphs depend on the type of function that is graphed. The eight most commonly used graphs are linear, power, quadratic, polynomial, rational, exponential, logarithmic, and sinusoidal. Each has a unique graph that is easy to visually differentiate from the rest.
Different Types of Graphs. If you transfer data from a table to a graph, the most immediate result is a scatterplot, which consists of a number of different points on the coordinate plane. In connecting those points, you arrive at a line graph. The horizontal axis functions the same in both of these cases. In a bar graph, however, the horizontal axis can take on a slightly different role. For example, if you are comparing the populations from three different years in a bar graph, the horizontal axis would merely have labels for each year.
