I am very interested in this capability too - is there a date that this functionality is expected to be included?
When I click the snapshot button, I can click any of the charts/graphs on the screen and it appears to take a picture of the chart at that time. There is a little camera icon that then appears in the top right of the chart, and if I click it, a list of snapshots I took appears. However, all I can do with that list is delete snapshots - I cannot open or see them. Is there a way to view them?
As a publicly traded company unfortunately we cannot be more specific about future product features but it does sound like you would benefit from Data Stroytelling.
The snapshots you are taking are for use in Data Storytelling. Look for the icon highlighted below to enter the Data Storytelling area.
The general work flow is you create a series of snapshots while performing you analysis and then go to the Data Storytelling to create a presentation to explain what you found out.
