Hi Can anyone recommend some open source projects for calculating and plotting point & figure charts with as many as possible options.

Thx

You might try the new R-package rpnf from http://rpnf.r-forge.r-project.org/.

It is able to produce Point & Figure Charts (with downloaded data from yahoo). Additional it identifies sophisticated Buy and Signals like Double/Triple Top/Bottom, Bullish/Bearish Signal for you. Furthermore it can be used to create Relative Strength Charts as well as Bullish Percent Charts.

Examples

A PNG-Plot can be seen here.

The best recommendation that I can give for creating an obscure chart format such as point & figure is to try and create it from the tools provided in Protovis. This library allows you to make custom charts, using chained DSL type function calls. Protovis gives you building blocks like labels, lines, and wedges to create your own custom chart visualization. They have numerous examples to get started and great documentation.

The only open source useable implementation I could find is point and figure. There is also Financio.

I'm not used neither one but since nobody answered yet I just pointed out some alternatives.

Here is a Java library (http://mov.sourceforge.net/api/org/mov/chart/graph/PointAndFigureGraph.html) that draws P&F charts. I've not used it though I do use P&F charts on a daily basis for trading.

Point and Figure graph. This graph draws a series of characters (X/O) mapping the general movement. A change in column shows a reversal such that price difference met the price scale.

Its not very robust, but then again, if you're writing custom or traditional indicators they wouldn't exist in this class anyways.

Hope this works.

Point & Figure is one of the supported chart types in the DataVisualization libraries included in .NET 4 (System.Windows.Forms.DataVisualization.Charting and System.Web.UI.DataVisualization.Charting)
