5.3 Comparing One Column to Another

Building upon the Distribution platform, the answers to questions you asked about one column have motivated you to ask further questions about the relationship between two columns. For example, what might be the relationship of profits to other columns in the data table? In fact you have already identified an interesting relationship between the company type and its profits using dynamic linking as some types of companies are associated with higher profits. This visual relationship implies something is happening with profits that includes more than just one column. You identified a relationship between the Profits column by another column called Type. This implies that there may be a relationship between at least two columns that we'll explore in this section.
