When multiple Samples are located at the same position, they can be displayed using three different modes on the map:

• as pie-chart, where the pies are filled with the group colors
• as small circles, where multiple circles are drawn filled with the corresponding group colors
• by Sample count, where the color represents the number of Samples that share the same position

• 

  as pie-chart

• 

  as small circles

• 

  by Sample count

The Sample Display Options dialog can be used to switch between these modes.

For the pie-chart, there are additional options:

• min. node size: the minimum size of a pie
• max. node size: the maximum size of a pie
• node size step: the amount a pie gets larger for each Sample at the position

For the Sample count mode, the colors and thresholds can be defined.
