I think you will need to set the data on the data object displayed.
Try:
pro iplot_animation_demo
; read in some data
data = randomu(seed, 512)
; create original iTool (getting ID for later use)
iplot, findgen(512), data, identifier=idPlotTool
itcurrent, idPlotTool
id = itGetCurrent(tool=oPlotTool)
; save Plot Vis' ID so we can come back to it later
idPlotVis = oPlotTool->findIdentifiers('*plot', /visualizations,
count=count)
oPlotVis = oPlotTool->getByIdentifier(idPlotVis)
for i = 0, 99L do begin
oDataX = oPlotVis->getParameter('Y')
success = oDataX->setData(randomu(seed, 512))
endfor
end
