The string "HEP" in the project name "jHepWork" abbreviates "High-Energy Physics". But due to a wide popularity outside this area of physics, it was renamed to [[SCaViS]] ('''S'''cientific '''C'''omputation and '''Vis'''ualization Environment).

==Examples==
 
===Jython scripts===
 
Here is an example of how to show 2D bar graphs by reading a CVS file downloaded from the [[World Bank]] web site.
 
<syntaxhighlight lang="python">
from jhplot.io.csv import *
from java.io import *
from jhplot import *
 
d = {}
reader = CSVReader(FileReader("ny.gdp.pcap.cd_Indicator_en_csv_v2.csv"));
while True:
    nextLine = reader.readNext()
    if nextLine is None:
        break
    xlen = len(nextLine)
    if xlen < 50:
        continue
    d[nextLine[0]] = float(nextLine[xlen-2]) # key=country, value=DGP
 
c1 = HChart("2013",800,400)
#c1.setGTitle("2013 Gross domestic product  per capita")
c1.visible()
c1.setChartBar()
c1.setNameY("current US $")
c1.setNameX("")
c1.setName("2013 Gross domestic product  per capita")
 
name1 = "Data Source: World Development Indicators"
 
set_value = lambda name: c1.valueBar(d[name], name, name1)
 
set_value(name="Russia")
set_value(name="Poland")
set_value(name="Romania")
set_value(name="Bulgaria")
set_value(name="Belarus")
set_value(name="Ukraine")
c1.update()
</syntaxhighlight>
 
The execution of this script plots a bar chart in a separate window. The image can be saved in a number of formats.
 
Here is another simple example which illustrates how to fill a 2D histogram and display it on a canvas. The script also creates a figure in the [[Portable Document Format|PDF]] format.
This script illustrates how to glue and mix the native JAVA classes (from the package java.util) and DataMelt classes (the package jhplot) inside a script written using the Python syntax.
 
<syntaxhighlight lang="python">
from java.util import Random
from jhplot import *
 
c1 = HPlot3D("Canvas") # create an interactive canvas
c1.setGTitle("Global title")
c1.setNameX("X")
c1.setNameY("Y")
c1.visible()
c1.setAutoRange()
 
h1 = H2D("2D histogram", 25, -3.0, 3.0, 25, -3.0, 3.0)
rand = Random()
for i in range(200):
    h1.fill(rand.nextGaussian(), rand.nextGaussian())
c1.draw(h1)
c1.export("jhplot3d.eps") # export to EPS Vector Graphics
</syntaxhighlight>
 
This script can be run either using DataMelt IDE or using a stand-alone Jython after specifying classpath to DataMelt libraries. The output is shown below:
 
[[File:Histograms_in_3D_showing_random_Gaussian_data.png|thumb|center|222px|3D histogram]]
 
===Groovy scripts===
The same example can also be coded using the [[Groovy (programming language)|Groovy]] programming language which is supported by DataMelt.
 
<syntaxhighlight lang="groovy">
import java.util.Random
import jhplot.*
 
c1 = new HPlot3D("Canvas")  //  create an interactive canvas
c1.setGTitle("Global title")
c1.setNameX("X")
c1.setNameY("Y")
c1.visible()
c1.setAutoRange()
 
h1 = new H2D("2D histogram",25,-3.0, 3.0,25,-3.0, 3.0)
rand = Random()
(1..200).each{ // or (0..<200).each{
// or Java: for (i=0; i<200; i++){
// if argument is required, you cann access it through "it" inside the loop:
// (0..<200).each{ println "step: ${it+1}" }
    h1.fill(rand.nextGaussian(),rand.nextGaussian())
}
c1.draw(h1);
c1.export("jhplot3d.eps") // export to EPS Vector Graphics
</syntaxhighlight>
 
[[Groovy (programming language)|Groovy]] is better integrated with Java and can be a factor three
faster for long loops over primitives compared to Jython.

SHORT DESCRIPTION

DataMelt is a software environment for numeric calculations, statistics and data analysis


DataMelt, or DMelt, is an environment for numeric computation, data analysis and data visualization. DMelt is designed for analysis of large data volumes ("big data"), data mining, statistical analyses and math computations. The program can be used in many areas, such as natural sciences, engineering, modeling and analysis of financial markets.

DMelt is a computational platform: It can be used with different programming languages on different operating systems. Unlike other statistical programs, DataMelt is not limited by a single programming language. Data analysis and statistical computations can be done using high-level scripting languages (Python/Jython, Groovy, etc.), as well as a lower-level language, such as JAVA. It incorporates many open-source JAVA packages into a coherent interface using the concept of dynamic scripting.

DMelt creates high-quality vector-graphics images (SVG, EPS, PDF etc.) that can be included in LaTeX and other text-processing systems. The program runs on Windows, Linux, Mac OS.

History

DataMelt has its roots in particle physics where data mining is a primary task. It was created as jHepWork project in 2005 [1] using the Java software concept for International linear collider project developed at SLAC. Later versions of jHepWork were modified for general public use (for scientists, engineers, students for educational purpose) since the International Linear Collider project has stalled. In 2013, jHepWork was renamed to SCaVis. In 2015 it became a community-supported project and was renamed to DataMelt.

DataMelt is hosted by the jWork.ORG portal[2].

Documentation

In 2018, DataMelt web page hosted about 600 examples written in Jython, Java, Groovy, JRuby, covering a number of fields, from general mathematics to data mining and data visualization. The Java API documentation includes the description of more than 40,000 Java classes. The DataMelt documentation includes certain restrictions for general public due to the proprietorial nature of the documentation project.


jHepWork was described in the book "Scientific Data analysis using Jython Scripting and Java" [3]. Later it was also discussed in the German Java SPEKTRUM journal [4]. More recently, the DataMelt program was described in the book [5]. According to the Springer International, this book was top 25% most downloadable books in 2016 and 2017 in the category "Advanced Information and Knowledge Processing".

Comparisons of DataMelt with other similar packages for statistical and numeric analysis are given in these resources [6] [7] [8] [9] [10] .
