The Right Chart Pie charts and bar charts are best when comparing discrete values. Pie charts are okay for comparison of large granular data, but bar charts are better for comparison because order is easier to detect.
Scatter Plots Best when comparing the relationship between two sets of data (e.g. dependent and independent variables.)
Histograms Provides a count of groupings often based on either ranges or classification
Line Graphs Line graphs are like scatter plots in that they record individual data values as marks on the graph. The difference is that a line is created connecting each data point together. In this way, the local change from point to point can be seen. This is done when it is important to be able to see the local change between any to pairs of points.
