In addition to the word trees and word clouds discussed in the Searching page of this module, NVivo can also be used to create other visualisations in the form of charts, maps, and diagrams. This page provides two such examples; creating a chart and creating a mind map. In order to follow some of the examples, you should make use of the Environmental Change Down East sample project (as detailed in NVivo sample projects).
NVivo allows you to create charts to visualise various aspects of the codes, files and cases in your project. For example, you could create a chart to show how many of each reference type exist in the sample project, using the Reference Type attribute of the’ Reference’ file classification. You can do this as follows:
Note that you can edit your chart once created using the options available in the ‘Chart’ tab on the ribbon, and you can export, print or copy the chart by right clicking on it and selecting the required option from the menu.
For more information on charts, you may like to view the you may like to view the NVivo User Help - Charts online help.
You can create different types of maps to visualise ideas and displays connections and links in your NVivo project. In particular, a mind map can be used to display ideas and relationships and can be used to create codes, while a concept map can be used to define and connect concepts and a project map can be used to visualise items and links in a project. This section provides an example of how to create a mind map, but for more on this or on other types of maps you may like to view the NVivo User Help - Maps online help.
A mind map is a brainstorming tool that starts with a central topic or main idea. Ideas that relate to the central topic are represented by an individual shape and connected with a line to the main idea, either at the same level or in a hierarchy. Additionally, an idea that is not connected to any other ideas can be added as a floating idea in the mind map.
To create a new mind map for the sample project, do the following:
Note that you can use the menu items in the ‘Mind Map’ tab at the top of the screen to change the Fill, Border Colour and Border Width of various components of the mind map if necessary, and also to change the layout (e.g. to be top down).
To export or print your mind map, right click in the mind map area and select the required option from the menu. To create codes for items in the mind map, click on ‘Create as Codes or Cases’ in the menu and then click ‘OK’. The mind map will be converted into the themed code hierarchy under Codes in the List View (or under Cases if this option is selected).
