Removing operations in the data canvas

Some operations on your data can be removed in the data canvas.

For example, if a transformation has been added using the installed client but it is no longer applicable, you can remove it. Or, if you have deleted rows or columns from the analysis and you want to bring the missing data back, you can remove the delete-operation. To remove data sources or added rows/columns, see Removing a data source from a data table.

Procedure

  1. On the authoring bar, click Data canvas .
  2. Make sure the data table of interest is selected in the upper-left drop-down list.
    This step is only applicable if you have two or more data tables in the analysis.
  3. In the data canvas, click on the node where the transformation or operation you want to remove was applied.
    If there is an error in a transformation you will be guided to the affected node and transformation group by error icons.
    Note: If the transformation was added on a data loading-step, you will not be able to remove it from the web client. However, in an installed client, you can choose to edit the transformation and remove one or more transformations from the data loading-step.

    Details about the selected node are shown in the bottom left part of the data canvas.

  4. For the operation you want to remove, click Remove .

Example: Removing a 'replace value'-operation that is no longer applicable

There is an information icon on the node, as well as on the 'replace value'-operation in the step list. A tooltip gives you information about the issue:

Click to remove the operation.
