We try as much as possible to distribute Gatling and its side projects under Apache License v2.0. As much as possible means that we sometimes have to cope with some dependencies that are not Apache License v2.0 compatible or even not open source friendly.
Our sponsor, eBusiness Information purchased developer licenses, but as a consequence, this module cannot be open sourced and has to be developed in a separated project : gatling-highcharts. However, for convenience reasons, we distribute a ready to use bundle.

If Highsoft happens to change its licensing policy in a more open-source friendly manner, we’d gladly change our own.
