I'm thinking of the main window like this

+------------------------------+

|              |       |       |
|              +-------+       |
|              |       |       |
|              |       +-------+
|              |       |       |
|              +-------+       |
|              |       |       |
|              |       |       |
|              |       |       |
+------------------------------+

with a scrollbar at the bottom. Moving the scrollbar, its listener
would know how to adjust the six charts in sync with each other.

So no OHLC stock bars, but each open, high, low, close could be
plotted as individual lines?

How would the real-time updates work?
