Browse Tool

The Browse tool displays data from a connected tool as well as data profile information, maps, reporting snippets, and behavior analysis information in the data.

Use a Browse tool as you build a workflow to get insight that helps you prepare, cleanse, and analyze data. You can also use a Browse tool to view all data from a connected tool in the Results window. Without a Browse tool, the Results window displays up to 1 MB of data from a tool. See Results Window.

ClosedAdd a Browse tool

Connect a Browse tool to the output anchor of the tool that contains data that you want to view in detail.

There are three ways to add a Browse tool to a workflow:

The Browse tool requires temporary space and memory on your computer which increases the size of data and may impact performance. After you build a workflow and are ready to output results, you can disable Browse tools in the workflow.

To disable Browse tools in a workflow:

  1. Click the canvas to display the Workflow Configuration window.
  2. In the Configuration window, click Runtime.
  3. Select Disable All Browse Tools. The Browse tools in the workflow are grayed-out.

To enable Browse tools, deselect Disable All Browse Tools, in the Workflow Configuration window on the Runtime tab.

ClosedView data

View data in the Configuration window and the Results window. The Configuration window displays different charts and metadata depending on the type of data in the column selected in the Results window.

A colored data quality bar displays at the top of each column of data in the Results window.

By default, the first column of data in the Results window displays in the Configuration window. Click a different column to view its data in the Configuration window. See Results Window, for more on the Results window.

ClosedConfigure the view

The following options are available in the Configuration window:

  • Views: Depending on the type of data you are viewing, up to four tabs may display: Profile, Map, Report, Behavior Analysis. Two tabs can be viewed at once.
    • Single view: Click to view all tabs in a single window.

    • Left, right view: Click to view all tabs in the left and right halves of the window. Click different tabs in each window to compare data.

    • Top, bottom view: Click to view all tabs in the top and bottom halves of the window. Click different tabs in each window to compare data.
  • Data details: Displays the number of records, number of fields, and the file size.
  • Number of selected records: Displays the number of records selected. Click to clear the selection.
  • New window: Click to open data in a new, un-docked window. Data in the window will not change; this allows you to compare views and assess data after modifying and running a workflow. By default, the window name is the tool name and the tool ID of the Browse tool.
    ClosedRename a window
    1. With the Browse tool selected, in the Configuration window, click Annotation.
    2. In Name, type a name for the window.
ClosedView profile data

When a Browse tool is connected to a tool with string, numeric, or date/time data types, the Profile tab in the Configuration window displays a chart and metadata of the selected column. Click columns in the Results window to view data profile information for other columns.

By default, data profiling is enabled. To disable data profiling features, go to Options > User Settings > Edit User Settings and deselect Collect and display data profile information.

Charts

Select a column to see either a bar chart or scatter plot in the Configuration window. They type of chart shown is based on the type of data you select.

If the data stream contains a date/time column and you select a numeric column, correlation charts are shown. For example, sales data from one column may be combined with dates in another column to create a chart with sales per month. Use the arrows or chart icons to move between multiple charts.

Once more than 10,000 unique values are profiled, binning is applied to increase performance and to represent the data in a more meaningful way. Messages at the bottom of the chart indicate when binning is applied.

ClosedChart types

Bar chart

String (categorical) value types are profiled, sorted, and displayed in a bar chart. The bar chart depicts the frequency of a value, or grouped values, in data. A quality bar summarizes data quality.

ClosedData quality categories
  • NOT OK (Red): values contain leading or trailing whitespace
  • NULL (Yellow): no values were provided
  • EMPTY (Gray): strings with no values
  • OK (Green): values without leading or trailing whitespace, NULL, or empty values.
ClosedBinning

Data points are represented in a maximum of 100 bins. If there are more than 100 unique values, the full data set is profiled, but the chart displays the 100 most frequent values.

Scatter plot

Numeric value types are displayed in a scatter plot. The scatter plot depicts the distribution of data and includes a range (box-and-whisker) plot that identifies the lowest and highest values, and the first quartile, median or second quartile, and third quartile values.

ClosedBinning

Once more than 10,000 unique values are found, the data is represented as a bar chart displaying the 100 most frequent values.

ClosedChart display options

Hover over a chart to make multiple chart interaction options available:

  • Zoom : Enable the ability to zoom into a selected area of the data by clicking and dragging.
  • Pan : Enable moving around the chart by clicking and dragging.
  • Zoom in : Zoom into the current centered position. Alternately, use your mouse scroll wheel to zoom on the cursor position.
  • Zoom out : Zoom out from the current centered position. Alternately, use your mouse scroll wheel to zoom from the cursor position.
  • Reset axes : Select to reset the chart to the default view. Alternately, double-click the chart.
  • Toggle spike lines : Display dotted lines to assist in finding a data point's axis values.
  • Show closest data on hover : Reveal a data value using parenthesis.
  • Compare data on hover : Reveal a data value using axis labels.
  • Save as PNG : Save the current chart view as an image file.
