Bipolar Graphs

A sample bipolar graph looks like that below. It allows you to very compare two sets of data easily. Opposite adjectives are chosen and written down - some should be fact based, for examples ‘historical' and ‘modern'. Others should be value based, for example ‘ugly' and ‘attractive'. Different users can be asked to place a cross on a line between the pairs of adjectives, or assign a score for a particular variable
