Test Page Configuration

Before entering the "Run Test" page, the "Viewer" window appear.
It allows you to configure the type of graph that will later be displayed
in the Run Test page. It also allows you to view, in real time,
up to 4 parameters on the Y axis and 1 parameter on the X axis.

The parameters for this graph can be modified every time the test is changed, so a
personalized graph can be created for each test.
