Stem and lea plot

Boxes drawn either horizontal or vertical depicting graphical data are known as box plots.  This is a convient and effective manor of displaying relative information.  The example is comparing a machines ability to output energy.

Histogram

A Histogram is a a graphical representation of the distribution of data, shown as adjacent rectangles.  This example of sizes of fish could also be called a simple bar graph.

A Tiangular Plot is a plot that has three different data variables.  When using an equilateral triangle it makes it easy for the viewer to compare the three categories of data.  This particular example shows us a comparison of three ultramafic rocks found in this area.
