Amazon QuickSight Authors can now replace datasets in an analysis with a single click. This allows Authors to create analyses and publish dashboards using test data sets from spreadsheets or sample databases, and then easily replace these data sets as necessary. More details here.
Authors in Amazon QuickSight can now customize axis, column and legend titles to provide an optimized experience for Readers. Additional options now available include show/hide axis titles, set max and min for the axis range, and set increments on chart axes. More details here. Authors can also choose to display null data as zeros or blanks, or filter these values.
These updates are now available in both Standard and Enterprise Editions in all QuickSight regions - US East (N. Virginia and Ohio), US West (Oregon), EU (Ireland), and Asia Pacific (Singapore, Sydney, and Tokyo).
