Treemap 4.1 Documentation

Filter with Dynamic Query Sliders

.

Filter by Maximum Depth

See the section below on Aggregating the Lower Levels of the Tree

Filter by Attributes

• Slide one or both sides of the double sided sliders to the values you need. You can use as many sliders as you want.



• The nodes that do not fit the criteria you set with the sliders will appear grey on the treemap.
• Hiding filtered nodes: this is particularly useful to reclaim the pixels of the filtered out nodes to show more details on the remaining nodes. Note that the layout will most likely change drastically.

• Nodes could be hidden as you drag the slider but this can sometimes be too slow so it is done only when the option is set.

• NOTE: the "hide filtered nodes" will not be remembered in the save settings. The settings of the filters will be saved, but the filtered nodes will appear gray. If this is a problem, you can you the Export function of the file menu to create a new data file.

Hide Individually Selected Nodes

• To select nodes, click on the nodes or subtree border while holding the CTRL key down.



• The nodes' border will become dark blue.



• The nodes will be removed when you click on Hide Selected button.

Selecting a different filtering widget

• Right click on the name of the attribute and an option box will appear to change the widget.



• Nominal attributes will use by default:
  • Radio Buttons - if the number of attributes is between 0-2.
  
  
  • Check Box - if the number of attributes is between 2-4.
  
  
  • Item Slider - if the number of attributes is more than 4.
  
  
  
  

Aggregate the Lower Levels of the Tree

• By filtering by depth (the top slider in the Filter tab), you can aggregate the lower levels of the tree.





• The size is (by definition) aggregated using a "sum" function.



• The color is aggregated using the aggregation function selected in the legend tab. The default is the "average" function.



• Weighted average uses the size sttribute to weigh the average calculation.



• Click on an aggregated node and the aggregate numbers will be displayed in the detail table for the size and color attributes.
