A parallel chart is a visual chart that shows the differences in a collected amount of data.
When using the parallel coordinate plot for statistical data; considerations must be taken. The order, rotation, and scaling of the axis is important.

Star Plots
Star plots is a graphical map that displays many variables of data in a two dimensional chart of three or more variables shown on a axis. All data variables starts from the same point.
Star plots are also known as radar charts, polar charts, web chart, and spider chart.
Similarity Matrix
A similarity matrix is a matrix of data that expresses similar data between a number of data points. It is used to find clusters of data points and can be used to align sequences of DNA. The higher the score, the more similar the data. The lower the score the dissimilar the data.
Stem and Leaf Plot
A stem and leaf plot is used for depicting frequency among common numbers. The numbers are grouped with like numbers to show the frequency.
It uses quantitative data in a graphical form, similar to a histogram.
Box Plot
"This box plot reveals that machine has a significant effect on energy with respect to location and possibly variation"
A box plot is a graphical depiction of a set of numerical data. it is a convenient way of viewing the data through quartiles. You are able to see the differences between populations without making assumptions of the statistical data.
Histogram
Histograms are graphical representations of distributed data. It estimates the probability of the distribution of a continuous variable. The representation shows the variance of the frequencies; in intervals. The total area of the histogram must equal to the number of the data.
