Generalizing static tests plotting

[FrancescoNegri]

The plotting static tests is similar to the plotting of delay phases when the delay tends to infinite, as static tests are exclusively stopped manually, by pressing the mode button.
It makes sense, for generalization sake, to extend the function collecting and plotting data during delay phases such that it can go on indefinitely if a specific delay parameter (such as -1 or None) is passed to the function.
