Hi E-Chart team,

I have couple of queries on plotting incoming dynamic data (lets say 1 data
point every second) in a bar chart. I saw the below bar chart in your
website which looks like a good fit for plotting dynamic incoming series
data.

https://echarts.apache.org/examples/en/editor.html?c=dynamic-data

Questions :

   1. Your chart looks like a sliding window one. So is it like the user
   can see only the bars that are inside the window at given point of time?
   2. What happens to the old data that is going away in the left side?
   3. Can i show last 24 hours data points at any given point of time?
   4. Can we have zoom-in and zoom-out feature added to the above graph?

Quicker reply will be really helpful to me.

Thanks
Ayaskant
