A method prepares data for analysis. The method displays a user interface including a data flow pane. The data flow pane includes a flow diagram having a plurality of nodes, each node having an intermediate set and specifying a primary operation. When a user selects a node, the user interface displays a change list pane with an ordered list of secondary operations performed at the node and a data pane with rows from an intermediate dataset of the node. When the user provides input to perform an additional secondary operation at the node, the user interface (i) performs the additional secondary operation, (ii) determines a logical ordering for the additional secondary operation based on the primary operation of the node, (iii) adds the additional secondary operation to the change list pane according to the logical ordering, and (iv) updates the data pane in accordance with the additional secondary operation.
