Issue

Map is not automatically zoomed when opening a hyper file generated by Alteryx by Tableau Desktop 2018.1 and later.
In Tableau Desktop 10.5 and older, the map was automatically zoomed up when opening a hyper file including polygons generated by Alteryx.

Environment

  • Tableau Desktop 2018.1 and later
  • Alteryx

Resolution

Install Hyper API v0.0.11074 and later. The functions geo_auto_vertex_order and geo_invert_vertex_order is available to manipulate the vector order of polygons.
For more details about the functions, please see 2.14. Geographic Functions of the Hyper SQL documentation.

Cause

A hyper file generated by Alteryx uses a different winding order for polygons than the one used by Tableau. The functions geo_auto_vertex_order and geo_invert_vertex_order can be used to address the problem.
