According to the documentation, scatter( ) should be able to take either 2, 3, or 4 arguments (size and colors should be optional). However, the compiler tells me that there's no matching function call if I don't pass in all 4 arguments.
Steps to Reproduce
Install matplotplusplus with yay -S matplotplusplus. Inside CMakeLlists.txt, use find_package to find this external package.
# Your steps go here
mkdir build
cd build
cmake ..
make
./a.out

Additional context
I suspect that the AUR holds an outdated version of the package, that's why there's no variation flexibility in function arguments. Please consider updating the package in AUR.
