chart4s
Draw a web chart by Scala.
The charts are generated by C3.js. Support for other JavaScript libraries may come in the future.
Installation
Add the following to your build.sbt:
libraryDependencies += "net.pishen" %% "chart4s" % "0.2.0"
resolvers += Resolver.bintrayRepo("pishen", "maven")
Then, add the import statements to your code:
import chart4s.c3._Supported charts
