Voronoi tree widget
About the Voronoi tree widget
The Voronoi tree draws polygon cells around points on a plane in order to analyze questions of proximity. These widgets can also be useful for analyzing hierarchies of elements.
This article provides an overview of the configuration of this widget. See the Voronoi treemap article for more detailed information about generating and working with these diagrams.
The following table lists the configuration options of this widget:
|Widget title||Enter a descriptive title for the widget.|
|Widget description||Enter a description of the widget.|
|Widget size||Select the size of the widget window in the dashboard layout. The units are columns x rows. For example, 3x2 will fit the widget across three columns and two rows.|
|Time Range||The period of time for which you want to analyze data in a single view of the chart. You can choose from 1 hour up to 1 year.|
|Actions||Add or remove elements of the grouping field. Select All to include all values. These will create the polygons and sub-polygons of the treemap.|
|Field to show||Select from among the available aggregated fields.|
|Initializer||Select the required visualization type.|
|Operation||Choose None (real size) or Logarithmic|
|Show value||Select ON to show values when hovering the mouse over a node. If you select OFF, only percentages are shown.|
Select ON to show the cell's percentage in comparison to all other cells at the same branch and level in the treemap.
|Show total %||Select ON to show the cell's total percentages.|
|Show zero values||Set ON to include zero values in your treemap.|
|Max number of nodes||Specify the maximum number of nodes you want to include in the entire treemap.|
|Max number of nodes by level|
Specify the maximum number of cells you want to include at each level.
|Ascending scale||This determines which cells will be displayed when the Max number of nodes is a number smaller than the total available nodes. Select ON to display the n cells with the lowest values. Select OFF to display the n cells with the largest values.|
This example below uses a Voronoi treemap diagram to illustrate the origin of web hits over the last week by country and city of origin, then by ISP.
- Time Range is set to 1 week.
- Field to show is set to count.
- Actions is set to All. However, if we wanted to analyze only web traffic from the USA, then we would select US for country and All for the other fields, then add the Action.
