ZoomCharts Documentation

This field contains the ID of the source node (also known as “parent node” or “From node”). Source nodes are nodes that precede the specific data point in the hierarchy.

For example, if you want to create a relationship between nodes A and B where the latter succeeds the former, you must define A as the source node of B. 

Node IDs can be any combination of alphanumeric characters, but they cannot contain spaces. You can include multiple source nodes within the same row by separating their IDs with a comma (for example, “A,B,C”). In that case, all source nodes within the same row will share the same values and properties from the adjacent columns (e.g. Target Nodes, Value, Source Node Image / Color / Shape / Category Class etc.).
