Yes, several, thanks.

My current project I need to embed six charts into an app (not applet)
window. Each chart will have sub-plots of data. The number of plots
can range from nine plots (data series) to maybe 100 plots. The plots
are mostly lines, though in each chart window/panel there is one plot
of stock-style high/low/open/close bars. The plots all receive data
in real-time, though the way this works is the data comes in and each
plot's data series is updated with the new value. As is typical in
stock applications once the bar's time period has expired, the bars
is moved to the left (older) and a new bar plot is started. So each
plot will receive an update data value, then I need to somehow trigger
the data series to shift to the left (older) and start a new data plot.

My questions are many, though these are some:

- can jcharts work as I have described the app window
  - six charts in the primary app window
- can jcharts plot stock bars
  - I know it can do lines
- can jcharts handle the real-time update
  - if I need to manage the shifting of data to the left (older) that's fine
- can jcharts work with an application (not applet)
  - I deliver all jar files using JNLP
- one odd thing I want to do is to eventially sync all charts to a single scroll
  bar at the bottom of the window
  - so that by moving the one scrollbar all charts are properly scrolled

I think that's a good start. :)
