Treemap is a visualization that displays data in nested rectangles. Each rectangle represents a category and the size of the rectangle represents the category’s contribution to the whole. The size of rectangles is calculated using aggregation functions like count, sum, average, etc. The rectangles are arranged by size from top left (largest) to bottom right (smallest). Treemaps provide insights similar to a Pie chart but are more useful with a large number of categories, and are visually attractive too.

In the example below, Treemap is created with “Component” as a category, to analyze Jira issues.

To create a Treemap:

  • Right-click on the ‘Component(s) column > Select View> Change>Treemap.

  1. Data Configuration mceclip1.png: It lets you choose columns for the following settings:
    1. Category
    2. Rectangle Size
    3. Color saturation
    4. Sorting
  2. View Configuration mceclip2.png: It lets you configure the visual appearances and interactions of the Treemap.
    1. Label Style
    2. Legend
    3. Decimal Precision
    4. Container Settings
    5. Visual Interactions
  3. Visualization Level Filters mceclip3.png: They let you filter the data in the specific visualization without impacting other visualizations.       

Refer here to learn more about Visualization Level Filters.

  1. User-Defined Colors mceclip4.png: They let you add meaning to a data point by associating a specific color to it. User-defined colors also help you to differentiate a data point from the rest.

    2. Color Saturation Settings 

Data Configuration

  • Click on themceclip5.png icon for data configuration options.

Categorize By

You can specify the column to be displayed as categories in Treemap.

To change the column:

  1. Click on the mceclip6.png to remove the existing column.
  2. Drag the desired column from the Data Panel and drop it onto the Visualizations Panel’s “Category By” section.
Note.pngNote: You can also type the column name in the Data Panel to quickly find it.

Rectangle Size By

Here, you can specify the column to calculate the size of rectangles. 

To change the column:

  1. Follow the same steps shown in “Categorize By”.
  2. Click on the  mceclip7.png  icon to select the aggregate function.
  • Aggregate functions for textual data: Count, Unique Count
  • Aggregate functions for numerical data: Count, Unique Count, Sum, Min, Max, Avg

In this example, the rectangle size is calculated on the basis of the average time spent by assignees for solving issues.

Color Saturation By

You can use color gradients to show the progression of data from high to low values. Each rectangle will be colored with a shade from the spectrum between the colors defined as ‘Minimum’ and ‘Maximum’. 

To apply color gradients:

  1. Drag the desired column from the Data Panel and drop it on the Visualizations Panel’s “Color Saturation” section.
  2. Select the aggregate function by clicking on the mceclip8.png icon. 

In this example, notice how rectangles with light colors represent lower values and dark colors show higher values, calculated by Sum(Time Spent).

To customize the shades of color saturation, refer to section- ‘Color Saturation Settings’. 

Sorting

You can sort the rectangles of the Treemap on the basis of either Rectangle Size or Category. 

Note.pngNote: By default, a Treemap is sorted by the rectangle size.

To change the sorting order:

  1. Click on mceclip9.png icon and select the column from the drop-down.
  2. Click on mceclip10.png or mceclip11.png icon to select the sort order (ascending or descending).

Visual Configuration

  • Click on themceclip12.pngicon for visual configuration settings. 

Label Style

This lets you customize the look and feel of data labels shown in each rectangle of a Treemap.

  1. To turn labels on or off, select the toggle switch next to Label. 
  2. To display values, select the toggle switch next to Value.
  3. To display values in percentage, select the toggle switch next to Value %.
  4. Move the slider or provide the value for font size.
  5. Click on the icon and select a font color. To restore the default color setting, click on ‘Reset to Default’.

Legend

Legend helps you identify and correlate data on your chart. They provide an overview of the different data points on the chart along with the associated colors.

  1. To turn legends on or off, select the toggle switch next to Legend. 
  2. Select legend position (Left, Right).
  3. Enter the text to change the legend heading.

Note.pngNote: Click on legend items and related data will be highlighted in the visualization. 

Decimal Precision

  • Choose the number of decimal places you want to display values with.

Container Settings

  1. To show or hide the header and border, click the toggle switch. 
  2. Turn on the toggle switch to show the border for the container. Change the border color, style and width as shown below:

To learn more, refer to section ‘Configure Coordinated Visualization’.

User-Defined Colors

  • Click on the mceclip13.png icon for user-defined color settings.

Colors for Individual Data Item

It lets you add meaning to a data item by associating a specific color to it and differentiate some data items from the rest.

For example, the red and green color may be used to represent “Off Track” and “On Track” issues, respectively. Whereas, orange color may be used for the “Bugs” type of issues to draw attention.

To change the colors:

  1. Click on the mceclip14.png icon next to the data item for which you want to change the color.
  2. Select the color from the available color grid or click ‘More Colors’. 
  3. To restore default settings, click on ‘Reset to Default’.

Color Saturation Settings

The following figure shows the default color saturation settings for your visualization. 

17.png

You can customize the color gradient effects with the following settings:

Minimum and Maximum Color

  • Select the color from the color grid. 

18.png

Minimum and Maximum Numeric Values

  • Set the numerical values for ‘Minimum Value’ and ‘Maximum Value’. 

Numeric values are calculated from the column selected for ‘Color Saturation’ (in this example- Sum(Time Spent). You can provide custom values representing ‘Minimum’, ‘Center’, ‘Maximum’ Values. 

All rectangles larger than ‘Max Value’ are colored in ‘Maximum' color whereas those less than ‘Min Value’ in ‘Minimum' color.

19.png

Diverging Color Scales

  1. Select the toggle switch for ‘Diverging’. When Diverging is turned on, an additional color selector for mid-range value, called Center, appears. 
  2. Set the colors for ‘Minimum’, ‘Maximum’ and ‘Center’ separately.

Note.pngNote: Steps for color saturation settings  are same for Bar and Treemap chart.
