@saul_romero,
Animation happens only on first render of chart, as of now. And the code you have shared seems to be working fine with animation. Please take a look at this jsfiddle.
If this doesn’t fulfill your requirements or if you are facing any other issues, can you please create a jsfiddle and share it with us so that we can understand it better and help you out?
