Could you explain your issue in more detail? It appears you are trying to downgrade to RN 0.38 but I don't understand what you are trying to ask. Are you asking if its possible to use this charts library with RN 0.38? Have you tried? If you tried, did you get some kind of error? If so, what was it and what steps did you take to try and fix it?
Also, why not use a more recent version of react-native?
