Data Table
Displays attribute-value data in a spreadsheet.
Signals
Inputs:
- Data
Attribute-valued data set.
Outputs:
- Selected Data
Selected data instances.
Description
Data Table widget receives one or more data sets in its input and presents them as a spreadsheet. Data instances may be sorted by attribute values. Widget also supports manual selection of data instances.
- The name of the data set (usually the input data file). Data instances are in rows and their attribute values in columns. In this example the data set is sorted by the attribute "sepal length".
- Use 'Restore Order' button to reorder data instance after attribute-based sorting.
- Info on current data set size and the number and types of attributes.
- Values of continuous attributes can be visualized with bars; colors can be attributed to different classes.
- Data instances (rows) can be selected and sent to the widget's output channel.
- While auto-send is on, all changed will be automatically communicated to other widgets. Otherwise press 'Send Selected Rows'.
Example
We used two File widgets to read the iris and glass data set (provided in Orange distribution), and send them to the Data Table widget.
Selected data instances in the first Data Table are passed to the second Data Table. Notice that we can select which data set to view (iris or glass). Changing from one data set to another alters the communicated selection of the data instances if "Commit on any change" is selected.
