Are SPLINES possible?

[Forex Trader]

"Splines" as in "Cubic Splines" turn charts with jagged edges into charts with nice smooth curves because the hard data at every interval is used to find interpreted data at every 0.2 or 0.25 of the interterval. It would require being able to divide the BARS into sub-divisions like every 0.2 or 0.25.

Would this be possible? Is there a way to plot a fraction of a BAR?
