# finmath lib plot extensions

- - - -

**Convenient abstractions of some plotting libraries and example usages of finmath lib.**

- - - -

This project provides abstractions for some plotting libraries (JFreeChart, JavaFX, 

JZY3D) and demo usages for finmath lib.

It is provided for convenience to test and explore finmath lib.

Main features:

- Create 2D and 3D graphs (using JFreeChart (2D), JavaFX (2D) and JZY3D (3D)).

- Animated 3D visualization (using JZY3D (which uses OpenGL)).

- Save the graphs as PDF (using iText).

- Save the graphs as SVG (using JFreeSVG)

- Easy to use classes and methods with a default style.

## Usage

### Easy and lightweight plot creation

Aiming at quick creation of plots, plots can be specified using a function / operator (e.g. via a lambda expression) and a few parameters specifying the discretization:

		Plot plot = new Plot2D(0.0, 300.0, 100, function);

		plot.setTitle("Black-Scholes Model European Option Value").setXAxisLabel("strike").setYAxisLabel("value");

		plot.show();

where function is, e.g.,

		DoubleUnaryOperator function = (optionStrike) -> {

			return AnalyticFormulas.blackScholesOptionValue(initialStockValue, riskFreeRate, volatility, optionMaturity, optionStrike);

		};

(taken from `net.finmath.plots.demo.Plot2DDemo`).

### Live visualization or 'reactive plots'

The ``Plot2D``supports live updates and can be used as an observer registering to a 

(reactive) stream via

        plotable -> plot.update(plotable)

where `plotable` is a  `List` where a `Plotable2D` can be a function (`DoubleUnaryOperator`) 

or a series of `Point2D`.
