Numbering and layout method for flow charts
View Patent ↗A process for numbering flowchart elements populates a graphical display with a collection of flowchart elements and ranks the flowchart elements based on the flowchart elements' geometric location. The process separates the elements into ranked branches and trees, and numbers each element according to the chart element's position within the branches and trees, relative to the other chart elements.
1. A method for numbering flowchart elements comprising:
examining a chart node collection on a display surface with a link parser to count the number of inbound links on a chart node and generating a connection list;
configuring a root identifier with the connection list to identify the chart nodes with no inbound links as root nodes and add the root nodes to a root node list;
applying a geometric ranker to the chart node collection to generate a geometric rank comprising:
ranking a first chart node within the chart node collection based on the first chart node's first axis value relative to the chart node collection's constituent nodes;
ranking the first chart node within the chart node collection based on the first chart node's second axis value, if the first axis value for the first chart node is within a tolerance value of the first axis value of at least one of the chart node collection's constituent nodes;
adding the first chart node to an ordered enumeration list;
configuring the geometric ranker to rank a tree based at least in part on the geometric rank of the root node of the tree;
configuring the geometric ranker to rank a branch within the tree based on the geometric rank of the root node of the branch;
configuring the geometric ranker to rank the chart node within the branch based on the geometric rank of the chart node;
configuring the root identifier with the geometric ranker to identify the chart node, with the geometric rank that is the highest, as the root node and add it to the root node list, if none of the chart nodes in the tree have inbound links;
numbering the chart nodes comprising: configuring a sequencer with a numbering schema to generate a node number; and
configuring an associator with the node number and an enumerated chart node from the ordered enumeration list to associate the chart node with the node number; and
populating the chart node collection on the display surface.
2. The method of claim 1 , wherein the numbering schema is user-provided.
3. The method of claim 1 , wherein the chart node collection is populated on the display surface.
4. The method of claim 1 , wherein if the chart node has two parent-nodes the geometric ranker is triggered to rank both parent branches.
5. The method of claim 1 , wherein the process for numbering flowchart elements is triggered when the arrangement of the chart nodes is changed on the display surface.
6. The method of claim 1 , wherein the node number is displayed on the display surface.
