Hi!

I'm sorry but you need to explain what the problem is, why you think it's a 
problem in Flot and not in your code (if you suspect your code is the problem, 
please do not add issues here, use the Google Group where the chance of getting 
help is much higher), and lastly, condense the testcase to something as small 
as possible and self-contained. The above is neither as small as possible or 
self-contained, you failed to provide the data set.

yes you are right !
I make a mistake in my code !  
change this is code:
var axes = plot.getAxes();dataset = plot.getData();
for :
var axes = plot_big.getAxes();dataset = plot_big.getData();
that is ok !
