Ok, i'll just do a brief summary, coz i gotta go to sleep now...:P

Back to back Stem Plots- Used to display bivariate data: Numerical and Categorical (2 variables)
Parallel boxplots- Numerical and Categorical (more than 2 variables)
Percentaged Segmented Barchart- Used with 2 categorial variables showing the percentage of each.
Scatterplot- Two numerical variables
Two Way Frequency Tables- Used with 2 categorial variables
Histogram- If given class interval and frequency
Dot plot- Used with discrete data
