Data Inspector is capable of displaying data in four view modes: Table View, Single Record View, Text View and Hexadecimal View. You can switch between the view modes by clicking on the View Mode icon in Data Inspector's toolbar. A list of available view modes is based on the inspected element: data records for edges can be viewed in Table View and Single Record View; supported view modes for a component are based on the component's type.

Following actions are available from Data Inspector toolbar.

Refresh

The Refresh button lets you perform manual refresh of debug data.

Data is refreshed automatically when a graph run finishes and after performing actions that require refresh (applying a filter, switching the truncate option). Manual refresh might be useful, for example, when source file of inspected component has changed.

Keyboard shortcut: F5

Pin Data

Pin Data binds Data Inspector to a specific edge or a component. If you pin data , and another edge or component is selected, Data Inspector's content will not change. But it will still be automatically refreshed after a graph run is finished or when performing data inspection on the same edge or component.

If you open Data Inspector from the context menu and at least one unpinned Data Inspector already exists, the Pin Data option will be applied.

Lock Data

Lock Data locks the content of Data Inspector so that it is not refreshed automatically (e.g. after a graph run). Locked state also disables manual refresh, so data cannot be refreshed by accident.

	Tip
	Use Lock Data to view the differences between two graph runs.

Quote Strings in Lists

This action is available from the drop-down menu in the Data Inspector toolbar.

Displays items of the lists quoted. It makes it easy to see which comma is a delimiter and which one is a part of the list item.

Show View When Content Changes

This option makes the Data Inspector tab active when its content has changed.

Truncate Strings and Arrays

When Truncate Strings and Arrays is active, values of loaded data fields are truncated to the first 253 characters or array elements to improve performance when loading huge data records. Disable this option to show entire field values.

Show Unprintable Characters

Unprintable characters (line breaks, space characters, etc.) are displayed as a proxy character.

View Mode

Switches between view modes, see View Modes.

Open New Data Inspector View

This action opens a new view with the same content.

Tip: open a new data view and lock the old one. You will be able to see differences between two graph runs.

Additional actions are available from Data Inspector's menu or from context inside the view. The Data Inspector's menu can be accessed by clicking on the arrow in right side of Data Inspector's toolbar.

Copy

In Table View and Single Record View modes, you can copy either a whole table row (or more rows) or a value of a single cell. In Text View and Hexadecimal View, it is possible to copy a selected text.

Whole records can be copied by using Ctrl+C keyboard shortcut or using Copy item in the context menu. Fields in copied records are delimited by tabulators. If pasted into a spreadsheet (e.g. Microsoft Excel), they fill spreadsheet cells.

A single cell value can be copied by choosing Copy Cell from a context menu of the particular cell.

Hide/Show Columns

Actions for hiding columns are available only in Table View mode. They allow to select which columns will be displayed and which not. They are available from Data Inspector's menu under Hide/Show Columns or from a context menu of a column header.

Go to Line.../Go to Record...

Opens a dialog that requests a line number. After confirming the dialog, the requested record or line will be highlighted. If necessary, the dialog scrolls to display the record.

Keyboard shortcut: Ctrl+L

In Table View and Single Record View modes, it is possible to apply a filter to the displayed records.

In the right bottom corner of Data Inspector, there is a filter widget that shows the state of the filter. It also serves to modify the filter, clear the filter or disable it temporarily.

New Filter Expression

In a new Data Inspector, the widget in the right bottom corner shows the Filter is not set text. Click the text to open the Filter Editor and define a filter expression. For information on how to create filter expression, see Debug Filter Expression.

When you have created a filter, the text Filter is not set changes to Filter is active.

Disabling the Filter

You can disable the filter by clicking the Filter is active text. The filter is not applied and the text changes to Filter is not active.

An alternative way to disable the filter is to click the arrow next to the filter widget and choose Active from the menu. Tick before the menu item disappears.

Enabling the Filter

You can enable the filter by clicking the text again.

Another way to enable the filter is to click the arrow next to the filter widget and choose Activate from the context menu.

The Search Data allows you to look up a text in the records.

You can open the Search Data panel using the Ctrl+F shortcut, or by choosing Search Data... from the Data Inspector's menu.

Figure 30.7. Search Data

The search panel contains a text area where you can type an expression.

Next to the text area, there are the Mark all found matches and Case sensitivity buttons. If Mark all found matches button is checked, all found matches for the search expression are highlighted. If you enable the Case sensitivity option, the search will be case sensitive.

The Options... button gives you access to Search Options.

Search Options

Figure 30.8. Search Options

If Entire cells option is checked, the searched text must match the cell entirely.

If you check the Regular expression checkbox, the expression you have typed into the text area will be used as a regular expression.

Direction lets you choose a search order - you can search in direction of rows, or columns.

You can also select which column will be searched in: all, only visible or one column from the list.

The Bulb icon on the left side of the text area indicates that Content Assist is available by pressing Ctrl+Space.

The OK button searches for the first occurrence and closes the Find dialog.

The Cancel button closes the dialog.

You can export the debug data to CSV without a clipboard.

To export records to CSV click the arrow in the upper right corner and choose Export to CSV. You can use Ctrl+E as well. The CSV files can be subsequently loaded into a spreadsheet editor or processed by another graph.

Figure 30.9. Export Debug Data to CSV

When the directory specified by File URL does not exist, it is created before export of the file itself.

Export can run in the background and the user can do another work meanwhile. Progress is reported in Progress view in the bottom right corner of designer.

Data Inspector lets you change its default configuration. You can set up a preferred view mode, show/hide unprintable characters, truncation of strings and byte arrays and number of loaded lines/records.
