I would like to create a JAVA library, that will use an LGPL library. The LGPL library is a library that provides an API to create charts, whereas my library will provide a more high level API like creating a Window with a chart inside it. For example, I could have the following:
Proprietary windowWithChart = CreateWindowChart(); LGPLChart chart = windowWidthChart.getChart();
If I distribute my library as a JAR, is it mandatory to use an LGPL license, or can I use a proprietary license ? I'm wondering if my work could be considered as "a work using the LGPL library", or "a work based on the LGPL library"
