Sequential Icon Plots:
Sequential icon plots (or column icon plots) are a category of icon plots . For each unit, variables are represented as a sequence of bars with the height reflecting the value of the corresponding variable. Besides the order in the sequence, colors are usually used to identify particular variables. In other words, each unit is represented as a small bar chart.
Sequential icon plots are simpler than other icon plots, but they are not well suited for the first stage of analysis - spotting patterns. They are more suited to verifying hypotheses about patterns on the data.
