JCCKit is a nice and small library for creating scientific charts and plots.
Like
PlantUML, it's a very
text oriented solution written in Java.
The primary goal of
PlantUML is to document software, and in some occasions, having charts or plots can be usefull for that goal.
So even if
PlantUML has not been designed for charts/plots, it was easy to integrate
JCCKit.
The only change done was the of
colors recognized by
PlantUML.
You will have to refer to
the JCCKit User Guide to fully understand
the following examples. There is also a
PDF document for the configuration.
