Description: In order to avoid adding other declaration function for the same functionnality with other arguments, I had the possibility to pass extra-arguments in a tuple of variadic templates. The kwargs of matplotlib functions are accessible using a tuple of pair (string, T). T can be : bool int long double char* string vector of double vector of int vector of vector of double The syntax is not heavy, and if other types are needed, just implement a function such as std::pair analyze_key_value(const char* key, const T& value) { // Transform object of type T into an python equivalent type PyObject* pyobj = ....; return {key, pyobj}; } Some examples: streamplot vector> lw; // some code to fill lw plt::streamplot(x, y, u, v, make_tuple("color", mag, "linewidth", lw)); scatter // z is a vector plt::scatter(x, y, make_tuple( "marker", "o", "c", z, "s", z, "cmap", "inferno", "alpha", 0.5 ));
