Empty Source

The Empty Source task allows users to create datasets from scratch. In order to do that, users have to specify the Dimension (number of columns and rows) of the dataset and add the values into a Data Manager to graphically visualize them.

The Empty Source task is made of only one panel: the Options Panel.

The Options panel

Within this pane, users can find and set the following options:

• Number of attributes: it defines the number of columns your data should contain.

• Number of records: it defines the number of rows your dataset should contain.

• Case sensitive: users can select this checkbox if they want uppercase letters values to be considered different from the lower cases ones.

• Compress white spaces: select it to remove extra consecutive spaces from within strings. For example the string “university program” would be imported as “university program”.

• Strip spaces: select this option if you want to remove spaces surrounding strings. For example, the string “ class “ will be imported as “class”.
