You can give https://chartbrew.com/ https://chartbrew.com/ a try if you wish. You can make the API requests in a Postman-like interface directly on the platform. So you can have live-data coming in as the tool makes the requests automatically for you. You can also have multiple requests made to different services gathering data on the same chart. Disclaimer: I'm the creator of the tool, so feel free to ask any questions about it and I'll be happy to answer
