At Qonnections 2019 I hosted a session called "273367 Qlik Sense Visualizations, best practice and top tricks". Here's the app I used with all tips including test data. Tip titles, more details in app:
* Chart and UI * Butterfly chart Gantt chart Grid chart Dynamic charts Map image background Previous/next in selection Cyclic groups Dividers Date search filters Dynamic bookmark Select null
* Add ons * Above and below Color above average Bell curves Trendlines Accumulation Top 5 lines Offset measures
* Table * Custom report Change null color Sum with null Subtotals and empty rows Indentation Indicators and symbols Traffic lights Pajama striping Sparklines Link to app
I want to emphasize that many of the tips are invented by others than me, I tried to credit the original author at all places when possible. Many of the tips have been published before on the Qlik Community, the app below can be viewed as my current top picks.
If you liked it, here's more tips in the same style:
