A pie map (or a circle graph) is a circular[->0] chart[->1] divided up into sectors[->2], illustrating proportion. In a pie chart, the arc length[->3] of each sector (and then its central angle[->4] and flying field[->5]), is proportional[->6] to the quantity it represents. When angles are measured with 1 turn[->7] as unit then a number of percent is determine with the same number of centiturns. Together, the sectors create a full disk. It is named for its proportion to a pie[->8] which has been sliced.

A personal line of merchandise of credit chart or line graph is a type of graph[->9], which displays information as a series of data points connected by straight line segments.[1] It is a basic type of chart[->10] common in numerous fields.

A line chart is often used to visualize a trend in data over intervals of time a time series[->12] therefrom the line is often drawn chronologically.[2]


In statistics[->13], a histogram is a graphical representation showing a visual cast of the distribution of data. It is an estimate of the probability distribution[->14] of a continuous covariant and was first introduced by Karl Pearson[->15].



[1] A histogram consists of tabular frequencies[->16], shown as nigh rectangles[->17], erected over discrete intervals (bins), with an area equal to the frequency of the observations in the interval. The height of a rectangle is also equal to the frequency niggardliness of the interval, i.e., the frequency divided by the width of the interval. The total area of the histogram is equal to the number of data. A histogram may also be normalized[->18] displaying relative frequencies. It then shows the proportion of cases that fall into each of some(prenominal) categories[->19], with the total area equaling 1. The categories are usually specified as consecutive, non-overlapping intervals[->20] of a variable. The categories...If you want to get a full essay, devote it on our website: Orderessay
