Hi, @chiraggl
I chose not to use mvexpand.

Something like this should work for you, but you might need to play around with it a little to get the exact form you want (I didn't know if you had an _time field from these logs and if it correlated with the date stamp you had).

| baseSearch
| eval zip=mvzip('graph_data.ratings{}.y', 'graph_data.ratings{}x')
| mvexpand zip
| eval zip=split(zip, ",")
| eval ratings=mvindex(zip,0)
| eval time=mvindex(zip,1)
| eval _time=strptime(time, "%Y-%m-%d")
| timechart values(ratings) span=w

Essentially, zip each value pair together, expand them into their own rows, index out the values, create a _time field if it doesn't exist, then plug that into a timechart command. Hope this helps!
