GRAL

####

GRAL is a free Java library for displaying plots (graphs, diagrams, and

charts). The acronym GRAL simply stands for *GRAphing Library*.

Maintainer wanted

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

GRAL is looking for a new maintainer. If you are interested, please contact `[email protected] `_.

Features

========

- Ready-to-use classes for data management

- Data processing and filtering (smoothing, rescaling, statistics, histograms)

- Many different plot types: xy/scatter plot, bubble plot, line plot,

  area plot, bar plot, pie plot, donut plot, box-and-whisker plot, raster plot

- Legends: horizontal and vertical

- Various axis types: linear axes, logarithmic axes, arbitrary number of axes

- Several file formats are supported as data sources or data sinks (CSV,

  bitmap image data, audio file data)

- Exporting plots in bitmap and vector file formats (PNG, GIF, JPEG, EPS, PDF,

  SVG)

- Small footprint (about 300 kilobytes)

Usage

=====

Without build management system

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

You can just add ``gral-core.jar`` to the classpath of your project.

Using GRAL with Maven

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

If you want to use GRAL with your Maven project you will have to include it as

a dependency in your ``pom.xml``:

.. code:: xml

    

        de.erichseifert.gral

        gral-core

        0.11

    

Using GRAL with Gradle

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

.. code:: groovy

    dependencies {

        compile group: 'de.erichseifert.gral', name: 'gral-core', version: '0.11'

    }

Using GRAL with sbt

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

.. code:: scala

    libraryDependencies += "de.erichseifert.gral" % "gral-core" % "0.11"

Building GRAL from source code

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

The source package contains all files necessary to build GRAL from scratch using

the `Gradle `__ software project management and

comprehension tool. Like ``Makefile`` files the ``build.gradle`` files are used by

Gradle to generate various distribution or documentation files.

Building a JAR file of the library core

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

In case you just want to build the core of the library to get started execute

the following command in the ``gral-core`` directory::

  $ gradle assemble

This will generate a JAR archive named ``gral-core`` in the ``build/libs`` directory.

This JAR file can be added to the class path of your application.

Building a JAR file of the examples

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

In case you just want to build the core of the library to get started execute

the following command in the ``gral-examples`` directory::

  $ gradle assemble

This will generate a JAR archive for the examples in the ``build/libs`` directory

which can be used together with the library core to run example applications.

Building the documentation

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

The GRAL Gradle project offers three sources for documentation:

1. The JavaDoc files that can be generated with::

     $ gradle javadoc

2. The reports found in ``build/reports`` containing a project various

   information like test results, test coverage, etc. To build these files

   just execute::

     $ gradle report

3. A book-like documentation in the reStructuredText format is available in the

   file ``documentation_en.rst``.

Using GRAL in an IDE

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

The Gradle project can also be used in your favorite development environment like

Eclipse or NetBeans. For further information look at the following descriptions

on the Gradle website `http://www.gradle.org/tooling`

Once you have installed an appropriate Gradle plug-in for your IDE you will be

able to import the GRAL project found in this folder.

Requirements

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

To build GRAL from source, you need a Gradle version higher than 4.0 and at least Java 7.
