Automatically generating a sub-graphical program in response to user input configuring a graphical program node

A computer-readable memory medium comprising program instructions for configuring a first graphical program node in a graphical program, wherein the program instructions are executable to implement:

• displaying the first graphical program node in the graphical program in response to user input, wherein the graphical program comprises a first plurality of interconnected nodes that visually indicate functionality of the graphical program, and wherein the graphical program is executable to perform the functionality;
• receiving user input configuring the first graphical program node to perform a desired operation;
• automatically generating graphical source code to perform the desired operation based on the user input configuring the first graphical program node, wherein the graphical source code comprises a second plurality of interconnected nodes, wherein the graphical source code is automatically generated without user input directly specifying the graphical source code;
• wherein the automatically generating is performed without user input directly specifying the second plurality of interconnected nodes or connections between the second plurality of interconnected nodes.

A method for creating a graphical program, the method comprising:

• assembling at least a portion of a graphical program, wherein the graphical program comprises a first plurality of interconnected nodes that visually indicate functionality of the graphical program;
• displaying a first node in the graphical program, wherein the first node is configurable to perform at least one of a plurality of possible operations depending upon user input specifying configuration information for the first node;
• receiving user input specifying at least one first operation for the first node;
• and
• configuring the first node to perform the at least one first operation, wherein configuring the first node comprises automatically generating graphical source code for the first node to implement the at least one first operation, wherein the graphical source code comprises a second plurality of interconnected nodes, wherein said automatically generating comprises automatically generating the second plurality of interconnected nodes without receiving user input specifying the second plurality of nodes or connections between the nodes.
