All of the Professional licensing options (see here for details) include the JHawk Data viewer. The data Viewer uses data exported to XML files in the JHawk Metric Interchange format. This is a summary of the data collected by JHawk which can be used to reconstitute any of the JHawk metrics. By importing a number of files you can compare the values of metrics in a body of source code over time.

There are five main tabs in the Data Viewer -

• The File Select tab
• The Text Compare tab
• The Dashboard compare tab
• The Graph Compare tab
• The Visualization tab

The Demo download includes more documentation relating to the DataViewer. You can download it here.

File Select and Analyse

This allows you to select the Files to be compared in the data viewer. You can select all the files in a directory, add and remove files and alter the order in which the files are compared.

The Text Compare tab

The Text Compare Tab shows the differences between any two builds in text format. The differences can be viewed at all levels from System down to Method. You select the two builds to be compared in the drop down boxes at the top. By default the first and last builds are selected and the differences at System level are shown.

The Dashboard Compare Tab

The dashboard compare tab allows you to select two builds and compare them using the dashboard style tabs used in JHawk. By default the first and last builds are selected and the differences at System level are shown. The Package and Class sub-tabs allow you to select the package or class whose data you wish to view. If you select a package or class in one tab the data for this will be selected in the other tab if the data is available.

The Graph Compare Tab

The Graph tab gives a graphical representation of the changes in data over the builds selected for analysis. The Graph and the available metrics will change according to the level selected in the top left panel. Data will be displayed at System, Package, Class and Method levels.

The Visualization Tab

The Visualization Tab allows you to select data for display using Googles Visualization tools.At present both the Motion Chart and Data Table visualizations are available.
When you have created the HTML using the visualization tab you can then view it using your browser.
