Some data sources don't give back data with timestamps. For example the Twitter API can't tell you how many followers you had a week ago. It can only tell you how many followers you have today.
Luckily, Grow takes snapshots of metrics so you can see the metric history.
Let’s say you want to see how a metric looked in the past (yesterday, last week, last month). We’ve got a button for that!
Go to one of your metrics and expand it.
In the upper left-hand corner of your metric, you'll see three buttons. The click with the counterclockwise arrow shows you the snapshot history of your metric.
This will show all of the snapshots for the last month or so. Clicking on one will show you what the metric was at that time.
To change how often Grow takes a snapshot of the metric, go to Edit metric, then click on Snapshot Interval in the header above your metric.
In the window that pulls up, you can set when Grow takes a snapshot of your metric. You can set the start time, the time zone, and the time period (daily, weekly, or monthly). When you have set your snapshot interval, click the blue Save button.
And that's it!
