Time series with range selector realtime ajax data


Please help me build a Time series , temperature chart with range selector whose data keeps updating dynamically.
I tried my own way of updating the chart from ajax call but it does not update the chart, in fact it doesn’t draw.
What I need is :-

  1. chart with temperature data on Y axis - from db
  2. Time stamp data on x axis - form db
  3. Range slider - range from beginning upto now
  4. Scroll effect - say for 5 min of time.
    I am hardly able to comprehend the documentation and build it. I learn from examples, please bear with me.
    If you need to look at my code I shall post it.

Thanks and Regards,
