I have data in a CSV file for the last 7 days.
I want to plot a graph using that CSV file, but the graph should look dynamic. I mean to say that it should plot data for one day and after 5 seconds, it should plot data for stating 2 days and after next 5 secs it should plot data for stating 3 days, and like that for next 4, 5, 6, and 7 days.
After each 5 secs it will change value and it looks like moving graph.
It can be done! However, your question is now moving into the realm of Custom Visualizations within Splunk, which takes some development time. If you are new-ish to Splunk, just take the default timechart and go, otherwise we could have whole discussions on how to make this work.
