jfxplot

JFXPlot is a plotting library that can be used with Renjin, the JVM-based interpreter for the R language ( http://renjin.org )

This code is mostly an experiment in learning about R graphics, Renjin, and testing the possibility of adding graphics to Renjin.

The plot and barplot commands currently work by using the JavaFX chart library.

A prototype of a Graphics Device that uses the JavaFX Canvas is included.

Example

Add the jar file, plot-0.1-SNAPSHOT.jar, to the renjin dependencies directory.

Load in library and create some test data

import(org.jfxplot.PlotApp)
import(org.jfxplot.GraphicsState)
library(org.jfxplot.plot)

x = seq(-2.0*pi,2.0*pi,4.0*pi/100)
y = sin(x)

data <- c(1.0,2.0,3.0,4.0,5.0,6.0,7.0,8.0,9.0)

m <- matrix(data,3, 3)
m <- m * 100.0
rownames(m) <- c("A","B","C")
colnames(m) <- c("X","Y","Z")

Plot x,y data

plot(x,y)

Create new JavaFX Stage and plot barplot

dev.new()
barplot(m)

Create new JavaFX stage and show example of canvas. Canvas is an example of an R graphics device built-on the JavaFX Canvas

dev.new()
canvas()
