7 Jun 20172 minutes to read

You can decide on the visual representation of nodes belonging to all the treemap levels using the itemsLayoutMode property of the TreeMap.

There are four different TreeMap layouts such as

• Squarified
• SliceAndDiceAuto
• SliceAndDiceHorizontal
• SliceAndDiceVertical

Squarified

Squarified layout creates rectangles with best aspect ratio.

HTML

<ej-treemap id="treemap"  [dataSource]="population_data" itemsLayoutMode="squarified"
                          weightValuePath= "Population"  colorValuePath= "Growth">
     <e-levels>
         <e-level groupPath="Continent" [groupGap]=5></e-level>
     </e-levels>
</ej-treemap>

SliceAndDiceAuto

SliceAndDiceAuto layout creates rectangles with high aspect ratio and displays them sorted both horizontally and vertically.

HTML

<ej-treemap id="treemap"  [dataSource]="population_data" itemsLayoutMode="sliceanddiceauto"
                                 weightValuePath= "Population"  colorValuePath= "Growth">
    <e-levels>
         <e-level groupPath="Continent" [groupGap]=5></e-level>
    </e-levels>
</ej-treemap>

SliceAndDiceHorizontal

SliceAndDiceHorizontal layout creates rectangles with high aspect ratio and displays them sorted horizontally.

HTML

<ej-treemap id="treemap"  [dataSource]="population_data" 
        itemsLayoutMode="sliceanddicehorizontal" weightValuePath= "Population"
        colorValuePath= "Growth">
       <e-levels>
           <e-level groupPath="Continent" [groupGap]=5></e-level>
       </e-levels>
</ej-treemap>

SliceAndDiceVertical

SliceAndDiceVertical layout creates rectangles with high aspect ratio and displays them sorted vertical.

HTML

<ej-treemap id="treemap"  [dataSource]="population_data" 
       itemsLayoutMode="sliceanddicevertical" weightValuePath= "Population"
                                                  colorValuePath= "Growth">
     <e-levels>
        <e-level groupPath="Continent" [groupGap]=5></e-level>
     </e-levels>
</ej-treemap>
