Scala.js bindings for Flot and example applications

To use as a library, just pull in from

https://jitpack.io/#fancellu/scalajs-flot

Build Status

Example apps showing the use of Scala.js with Flot The bindings for Flot are under core com.felstar.scalajs.flot

Get started

To get started, run sbt ~example/fastOptJS in this root.

Obviously you need to have SBT installed.

This should download dependencies and prepare the relevant javascript files. It then kicks off a web server to serve the html and JS files. The example files are under example.

If you open localhost:12345/example/target/scala-2.11/classes/flot1-dev.html in your browser, it will show you a sample app, drawing 2 graphs. Do open the Console to see debug messages. There are also 2 other code samples.

Development

If you change your source HTML (inside /example/src/main/resources) or Scala (inside example/src/main/scala/example), sbt will recompile as needed. You then just have to refresh the page to see the new version. Hopefully having an example application will make it clearer on how to use Flot from Scala, i.e. monkey see, monkey do.

The optimized version

Run sbt fullOptJS for an optimized version of the final application, useful for final publication. You may well need to copy over XXX-dev.html to get your latest changes. Be sure to refer to the correct JS as well, as it will have a different name than the fast compiled version. e.g.

<script type="text/javascript" src="../scala-js-flot-js-example-opt.js"></script>

Eclipse integration

If you want to edit in Eclipse (can't compile yet, but still very useful having full IDE with code completion), just run sbt eclipse the open the generated .project file inside eclipse. Keep sbt running in order to do the JS Compile. https://github.com/typesafehub/sbteclipse/wiki

Status

This is just a quick proof of concept and some bindings for those wanting to use Flot from Scala.js. Feel free to get in contact with any issues etc.

You can’t perform that action at this time.
