chartjs-java-model

Provides Java models for Chart.js so that e.g. a Java Server can build a chart and then instruct a JavaScript client what needs to be shown.

This repo extends the abandoned Chart.java and adds support for Chart.js Version 4+.

Note

We try our best to implement the ChartJS v4 API however there are a lot of configuration options.
Therefore some parts might still be missing or use the outdated v2 API from the original repo.
If you think you found a missing or incorrect API please open an issue and/or provide a pull request.

Usage

Configuring a chart is straight forward and follows a builder like pattern:

new BarChart(new BarData()
  .addLabels("A", "B")
  .addDataset(new BarDataset()
    .setLabel("X")
    .addData(1)
    .addData(2)))
  .toJson(); // Do something with the json like sending it to the client

If you need more examples:

• Have a look at the demo
• or checkout how we do it in our tests
  • there are also screenshots available
