Good news! We are rolling out a new visualisation of survey trend over time. If you have asked the same questions on multiple surveys, we will automatically form those into question and factor trends, as shown in the image below.
The Trend chart is filterable, and is available on both overall and shared reports.
If you don't see Trend on your account yet, stay tuned – we're rolling it out gradually over the next few days.
You can find more detail in this article.
