I have several xy scatter graphs where one indicator is based on price,
another based on volume and they are charted on the x and y axes. The
tendency is for the resulting graphed line, when 10 or so data points are
graphed, to "circle" counterclockwise because the volume moves slightly
ahead of the price data.

My question is whether there could be a way to show that same action but to
have the chart scrolling along as the trading day goes on, say using time to
move it along horizontally while maintaining the circular motion provided by
the two inputs.

My data feed is real-time. I suppose the resulting graph I'm trying to
articulate might look like a long series of lowercase letter e's strung
together moving across the screen from left to right.

Can anyone suggest a possible solution? My thanks in advance. BR
