Hi Andrew,

If you're talking about animating 2d charts have a look at these tcl 
examples:
/Hybrid/Testing/Tcl/xyPlot.tcl
/Hybrid/Testing/Tcl/xyPlot2.tcl
/Hybrid/Testing/Tcl/xyPlot3.tcl
/Hybrid/Testing/Tcl/xyPlot4.tcl

And this C++ example:
/Widgets/Testing/Cxx/TestSplineWidget.cxx


Basically, vtkXYPlotActor is the class you want...

If you're talking about plotting your 3D data in 3D space have a look at 
vtkGlyph3D for a 3D scatter plot, and vtkPolyLine or vtkCardinalSpline 
for a line plot.

The also an example of plotting financial data here: 
/Examples/Modelling/Cxx/finance.cxx
