In the book « Show me the numbers », there is a table p. 310 in appendix A « Table and graph design at a glance » whose title is « Graph selection matrix ». This summary table is extremely useful for choosing what graph to make depending on the data series one has to deal with.

My question is about the types of uses when this « Graph selection matrix » can be looked at as a reference. The book « Show me the numbers » is focused on the use of tables and graphs for the purpose of communication. Consequently, should one use the « Graph selection matrix » only for the purpose of data communication or does this table also provide guidelines for other purposes, such as data analysis or monitoring ? I suppose that the « Graph selection matrix » can actually be applied in any case, each time someone has to design a graph, for I don't see any reason why it shouldn't. But I'm not completely sure about this.

Could you elaborate on that matter please ?
