This topic describes the ways you can customize a tree map to suit your analytical approach.
What do you want to do?
- Zoom in or out of a tree map
- Change the items displayed on a tree map
- Change the order of attributes displayed on a tree map
- Change the colors displayed on a tree map
Zoom in or out of a tree map
To quickly zoom in or out:
-
On the Status bar, click the Zoom slider.
-
Slide to the percentage zoom setting that you want.
To choose a particular zoom setting:
-
On the View tab, in the Window group, click Zoom, and then select the required zoom level.
Change the items displayed on a tree map
-
On the Tree Map tab, in the Options group, click Select Data.
The Tree Map Options dialog box opens.
-
Make any required changes—refer to Create a tree map for more information about the options.
-
Click OK.
Change the order of attributes displayed on a tree map
You can change the order of attributes that are displayed on a tree map that compares attribute value combinations—this can give you a new perspective on the range of sources or nodes in your project.
-
On the Tree Map tab, in the Options group, click Select Data.
The Tree Map Options dialog box opens.
-
Click an attribute in the Attribute Selection list on the right, and then click the Up or Down button.
-
Click OK.
Change the colors displayed on a tree map
If you are using color to show coding information (for example, Number of Nodes Coding), you can change the color spectrum used to show this information. By default, NVivo uses the Green-Yellow-Red spectrum.
If you have assigned colors to sources or nodes, you can display the item colors on the tree map—items with no color are displayed in white.
You can also turn off colors completely.
On the Tree Map tab, in the Options group, click Color Scheme, and then do one of the following:
-
To show source or node colors, click Item Colors.
-
To turn off colors, click None.
-
To change the color spectrum (only available when using color to show coding information), click the color spectrum you want to use.
