Stem and Leaf Plot


A stem and leaf plot is similar to a histogram but instead summarizes the set of information and then provides additional data. The numbers above are listed from greatest to least vertically and least to greatest horizontally.  They are also divided up by tens.

Box Plot

 A box plot is an easy way to graph five sets of data: the minimum, lower quartile, median, upper quartile, and the maximum. A box plot may also indicate if there are any outliers. This particular box plot that is used as an example shows the different speeds of light.

Histogram


 A histogram shows geographical information through the distribution of data. Histograms use bars to represent the information in the table. It also is similar to a population profile, having information both on the horizontal axis and the vertical axis.

Parallel Coordinate Graph

The parallel coordinate graph demonstrates a geometrical method to scale dimensions through parallel lines. Lines will usually begin at the lowest possible value and then fluctuate throughout the graph.

Triangular Plot


A triangular plot has three variables that sum up to a constant. It depicts rations of the three variables in an equilateral triangle. This type of map happens to analyze the different soil types, with the three variables being clay, silt, and sand. 

Windrose


 Windrose is used by meteorologists to determine the speed and direction of wind in a particular region. Windroses were designed after compasses. The windrose also uses colors to determine the variety of wind speeds.

Climograph

 A climograph shows the basic climatic parameters of both precipitation and temperature, as shown in the graph above. This picture has the months on the horizontal axis with both the temperature and the precipitation on the vertical axis.
