Plot of Tetration: $y=\mathrm{tet}_b(x)$ versus $x$ for

$b \rightarrow 1$,
$b = 1.1$,
$b = 1.2$,
$b = 1.3$,
$b = 1.4$,
$b = \sqrt{2}\approx 1.41,$
$b = \exp(1/ \mathrm e) \approx 1.44,$
$b = 1.5$,
$b = 1.6$,
$b = 1.7$,
$b = 1.8$,
$b = 1.9$,
$b = 2$,
$b = \mathrm e \approx 2.71$,
$b = 10$,
$b \rightarrow \infty$.

The fit is used, that provides several decimal digits, that seems to be sufficient to provide the "camera-ready copy"; the errors of the fitting are not seen even at the zooming-in.

This image is used as figure 17.2 of book Superfunctions [1].
