The Detailed View (parametric plot). In the display is shown the dependence relationship among the selected genes. The ordinate axis indicates the expression level while the abscissa indicates the parameter of the function that describes the relationship. The lines represent the expression level of the compared genes for each point of the relationship. Selecting any point of the relationship, a sample class is defined with the samples belonging to this relationship stretch. In the display, it is shown that ENO2 has an expression phase and a non-expression phase, with respect to the rest of the analysed genes.
