   @somdats I don't know if you are stuck with C++, or if you can use python. And how well you know about matlplotlib. Matplotlib-cpp is just a cpp wrapper of the python library matplotlib.

   What you want to do is possible with the python original library:
   https://matplotlib.org/gallery/axes_grid1/parasite_simple.html#sphx-glr-gallery-axes-grid1-parasite-simple-py

   But I don't know if this C++ wrapper as implemented this feature yet.

   Good luck,
   Jimmy

   Hello Thanks for your reply. I am stuck with c++. I could see many solutions for the same in python script however i am using the matplotlib-cpp wrapper which currently may not have the implementation. Alternatively i could add the functionality to the wrapper, however i lack the knowledge in its exact implementation

   Thanks for raising this, and sorry for the long silence. A secondary y axis fits the project: pyplot's twinx() creates a twin axes and makes it current, so a C++ plt::twinx() (and plt::twiny()) wrapper would let later plt::plot calls draw on the secondary axis. A PR that follows the style of the existing no-argument wrappers (look up the function once in the interpreter, throw on failure) and adds a short example to examples/ would be welcome.
