Responses over time
Responses and the score by day or by week, so a change on the site shows up as a change in the line.
A survey’s headline is a number for its whole life, which hides exactly the thing you usually want to know: whether it changed. The timeline charts responses per day or per week, and for NPS, CSAT and CES the score over the same periods.
That makes a survey useful around a change. Ship a new delivery promise or a shorter sign-up form, and the question is whether satisfaction moved afterwards, which a lifetime average answers slowly and a weekly line answers at a glance.
Days with no answers are drawn as zero rather than skipped, so a quiet week looks like a quiet week instead of being closed up into a smooth line. Days are whole UTC days and weeks start on a Monday, so two people reading the same chart in different time zones see the same buckets.
Responses are timestamped by our server rather than by the visitor’s clock, so a phone set to the wrong year cannot put an answer in the wrong place on the line.
