Changing layer orders in a map chart
You can refine a map chart visualization by reordering the layers that are displayed. The layers displayed, top to bottom, correspond to the order of the layer list in the Map chart properties dialog, first to last.
Right-click the map chart visualization, and from the menu, click
The Properties popover is displayed, with the Map chart popover showing the current layers, in their layer order, top to bottom.
Click the layer of interest and drag it to its new position.
If the new location is the top of the list, or if the top layers have transparency applied to their appearance, the layer is displayed in the map chart.
