plotAlternativesValuesPreorder

Provider:ITTB
Version:1.1

Description

This web service generates a graph representing a preorder on the alternatives, according to numerical values taken by the alternatives (the “best” alternative has the highest value). Compared to the web service plotAlternativesValuesPreorder, some parameters are added. Colors can be used and the title of the graph can be typed. You can choose between an increasing or a decreasing order for the graph. It is also possible to show the name of the alternatives instead of the id, etc. The alternatives’ evaluations are supposed to be real or integer numeric values.

Inputs
