Another alternative would be to use Piecewise and custom ticks.

@matheorem Hi, have a look at "ToggleDynamicUpdating" perhaps ?

comment Making Multiple Curves with ListLinePlot for Fixed Increments
Hi, it just making a table with c1 as your first level; for each value of c1 it then considers the different values for inc and you'll end up with a table with dimensions (number of c1 x number of inc).

Why not Table[f[c1, c1+inc], {c1, 0, 4, 0.1}, {inc, {0, 0.2, 0.4}}] ?

Alternatively, try using exact coefficients.

As of 10.1 one could also use MinMax and save one evaluation.

comment Strange result of parameter-dependent definite integral
Possibly the same underlying reason why Integrate[Cos[k Exp[I t]], {t, 0, Pi}, Assumptions -> {k >= 0}] evaluetes to Pi while Integrate[Cos[k Exp[I t]], {t, 0, Pi}, Assumptions -> {k < 0}] evaluates to `I (Conjugate[CosIntegral[k]] - CosIntegral[-k]).

comment Derivative wrt to order of MacDonald function
FullSimplify[FunctionExpand[Derivative[1, 0][BesselK][1/2, z]]] might be somewhat closer.

comment Implicit hidden assumptions of Mathematica with Limit
Same with Series[(Sqrt[2] v)/Sqrt[v^2 - c^2 (1 - 1/c Sqrt[c^2 - v^2])], {v, 0, 1}].
