how to filt data smoothly

[Jake]

in my application, i need to control the data range shows in the chart by a sliding bar. when data changes, now, i use setDataXML(fitered data) to reset the chart, but this method will reinit the whole chart, which doesn't act as a smooth change.

is there any other method i can use in this case? Thanks!

I'm afraid, as of now, we do not have an alternative method for this.
