I have used Drupal for a lot of years for different purpose.

I did create a module for Drupal 7 so all the data from your LoRa nodes can be stored as nodes in drupal and then you can show them as graph or what ever you like - Drupal can do it all.

Download the module from this LINK to zip

Here in the drupal menu you will find some tabels or graphs which show some of my data.

The module is quite simple to get working.

Download module and install.
