[R-SIG-Finance] displaying a traditional stock chart

[Armstrong, Whit]

That sounds interesting.

I guess it depends on how far we choose to take the interaction.

The in house system that I used had drop down menus for applying
functions to the series in the plot.  Also, another really nice feature
was that you could click in the upper left hand corner and type any
expression which would then be added to the chart.  The expression could
be as simple as a variable name, or it could be a function applied to a
variable.

It sounds like something like that would be out of the question with the
SVG device, but for simple operations like zooming in and out, or
highlighting date ranges SVG could be the way to go.

Let me know if you would like to pursue this.

One other solution I have thought about is using Trolltech's Qt 4.2,
which has nice plotting facilities.  Now that it is available on Windows
as well as Linux/Unix it is a viable option. (this pdf has a simple
graphics view in it, page 2)

Thanks,
Whit
