ABSTRACT

We merely change the symbol. So a line can be represented in three ways as set out in Figure 7.22, below. This means that the chart is flexible to be a work in progress. Figure 7.22: the three means of attaching a line

Wigmore also had closed dots and open dots placed inside symbols to denote belief of individual pieces of evidence. Figure 7.23: symbols for belief and unbelief

Numbers

Each symbol on the chart is is numbered and relates to a list setting out brief narrative labels for the evidence represented by the symbol.
