Hi everybody!
I want to chart Point&Figure charts using JFreelib. For an example of how they look like, look here http://stockcharts.com/def/servlet/SC.pnf?c=emc,P (there's a nice applet available as well there; click on "Dynamic")
One way to look at such a chart is to see it as a XY table with "X", "O" or empty information at each [X][Y] location. Talking of the axes, the X axis mostly remain unused, and the Y axis has the price level for each row, indexed by Y.
Another way to see such a chart would be to take each column with the starting and ending coordinates as a single series within a XYDataset.
Any ideas about how to implement such a tabled data view with customized axes best in JFreechart?
Thanks for your input!
Ted
