        Charba - J2CL and GWT Charts library based on CHART.JS

======================================================



  

  

  

  

  

  

  

  

  

  



What's Charba

--------

[GWT Web toolkit](http://www.gwtproject.org/) doesn't have charting library available out of the box.

There are some open source charting libraries for GWT available to be used but with some constraints or unclear items:

 * internet connection needed

 * open source license not completely clear, sometimes with some obligations like to add specific labels

 * old packages not longer maintained

For all these reasons, **Charba** has been developed, leveraging on [Chart.JS](http://www.chartjs.org/) capabilities which are now available to GWT developers.

Not only GWT

------------

Even if **Charba** was born only as GWT chart library, as of version 3, **Charba** has been changed in order to be used not only in GWT but also with other DOM frameworks, based on [J2CL - JavaToClosure](https://github.com/google/j2cl), like [Google Elemental2](https://github.com/google/elemental2) or [Elemento](https://github.com/hal/elemento).

**Charba** has got an own DOM manager which allows to it to be independent from any other DOM frameworks (i.e. GWT, Elemental2 or Elemento) but it is providing a set of hooks in order to use it also over those frameworks.

Building

--------

To build **Charba**, you can check out the project and to run [Ant build.xml](https://github.com/pepstock-org/Charba/blob/6.5/build.xml).

The [Ant build.xml](https://github.com/pepstock-org/Charba/blob/6.5/build.xml) is able to build the 2 artifacts, related to the 2 distributions available.

The first distribution is a **Charba** file without any GWT dependency (but working on GWT anyway), consumable also in other [J2CL - JavaToClosure](https://github.com/google/j2cl) frameworks, like [Google Elemental2](https://github.com/google/elemental2) and [Elemento](https://github.com/hal/elemento).

To build the project, execute `buildBinary` target.

It creates a `charba-[version.release].jar` file in `dist` folder, ready to be included in your project.

The second distribution is a **Charba** file with a hard GWT dependency which contains charts widgets and code splitting capabilities.

To build the project, execute `buildBinaryGwt` target.

It creates a `charba-[version.release]-gwt.jar` file in `dist` folder, ready to be included in your project.

Installation

------------

Currently **Charba** is available on [MVN repository](https://mvnrepository.com/artifact/org.pepstock/charba).

It is available also on [GitHub releases](https://github.com/pepstock-org/Charba/releases).

If you are using [Apache Maven](https://maven.apache.org/):

```xml

    org.pepstock

    charba

    6.5

    

    6.5-gwt

```

If you are using [Apache Ivy](http://ant.apache.org/ivy/):

```xml

```

To install in your GWT project, both for GWT and for J2CL artifacts, you must the following configuration in your GWT project module configuration:

```xml

...

    

...

```

**Charba** is based on [JSINTEROP](http://www.gwtproject.org/doc/latest/DevGuideCodingBasicsJsInterop.html) method to integrate java script objects.

As the name suggests, JsInterop is a way of interoperating Java with JavaScript. It offers a better way of communication between the two using annotations instead of having to write java script in your classes (using JSNI).

Documentation

-------------

**Charba** documentation is published [here](https://pepstock-org.github.io/Charba-Wiki).

All **Charba** documentation will be maintained in [Charba-Wiki](https://github.com/pepstock-org/Charba-Wiki) project.

See [Charba showcase on GWT](https://pepstock-org.github.io/Charba-Showcase) to have a look what you can do with it.

See also [Charba showcase GWT source code](https://github.com/pepstock-org/Charba-Showcase) on GitHub as starting point, if you are going to use on GWT.

See [Charba showcase built by J2CL](https://pepstock-org.github.io/Charba-Showcase-J2CL) and based on [Google Elemental2](https://github.com/google/elemental2), to have a look what you can do with it.

See also [Charba showcase J2CL source code](https://github.com/pepstock-org/Charba-Showcase-J2CL) on GitHub as starting point, if you are going to use on J2CL.

The samples are going to reflect what CHART.JS samples are showing [here](http://www.chartjs.org/samples/latest/).

Continuous integration and quality gate

---------------------------------------

**Charba** is continuously built at every commit and merge in `master` by [GitHub Action](https://github.com/pepstock-org/Charba/actions?query=workflow%3ABuild).

At every build, **Charba** is also checked by [Sonar.io](https://sonarcloud.io/dashboard?id=pepstock-org_Charba) in order to have the pulse of its quality.
