Currently, there are eight types of nodes: Input field, Output field, Join field, Union field, Group by field, Data Filter field, Field Settings field, and Pivot field.

Current nodes can be categorized into two types:

1. Input/Output Node

Input: the origin of data used for selecting data to process

Output: the exit of the data stream (the result of data calculation) output as data stream output form

2. Data Processing Nodes

There are six types of data processing nodes including Join, Union, Group by, Data Filter, Field Settings, and Pivot.
The specific usage of each node will be explained in detail in this chapter.

Basic Settings

Where to Add

When there is a data stream, select data stream nodes from the left to design.

Adding/Deleting

You can add nodes by dragging and dropping; Clickor tap Delete on the keyboard to delete the selected node.

When you delete the node, all other nodes connected with it are disconnected.

Adding Join Lines

Only by adding join lines can nodes connect with each other and perform data calculations according to rules.

Renaming Nodes

Rename nodes to better distinguish data processing nodes.

Note:

Output cannot be renamed. Its name is from the data source form.

Data Preview

Data Preview is used to view processed data and help determine whether the data is right and meets business requirements.

Undo or Redo

When there is a false click, you can click or can click to cancel the undo.

You can also undo and redo the step-by-keyboard shortcuts:

1. Undo

Mac OS system: ⌘+Z
Windows system: Ctrl+Z

2. Redo

Mac OS system: ⌘+Y
Windows system: Ctrl+Y

Align

Select more than two data stream nodes to align and click Align in the tooler to set nodes.

There are six ways to align nodes:

Align	Aligning Types	Aligning Rules
Align Horizontally	Left	Align the left-most node of all selected nodes to the left
Center	Align the left-most and right-most node of all selected nodes to the center
Right	Align the right-most node of all selected nodes to the right
Align Vertically	Top	Align the top-most node of all selected nodes to the upward
Middle	Align the top-most and bottom-most node of all selected nodes to the middle
Bottom	Align the bottom-most node of all selected nodes to the downward

Preview:

Layout

Select three or more nodes and adjust them to stay equidistant to allow nodes equally distributed horizontally and vertically.

There are two types of Layout:

Horizontal
Vertical

Canvas Scale and Navigator

When there are multiple data stream nodes, you can adjust the canvas scale to check the data stream settings. You can also use Navigator to find the location of data stream nodes.
