Block Shapes
Flowchart Maker supports all the flowchart shapes defined by Excel.
To find these shapes inside Excel, go to Excel’s "Insert" ribbon tab, in the "Illustrations" group, there are 28 items in the "Flowchart" section.
Connectors
Excel defines three types of connectors: Straight, Elbow, and Curve.
You can choose the connector type before creating a diagram. To do this, go to the "Flowchart" ribbon tab, and from the "Connect Type" list, choose the connector type you want. "Auto" means if two blocks are on the same axis, then it uses a straight connector; otherwise, it uses a curve connector.
Decision Labels
Decision labels are annotations added to connectors. They are usually added to connectors originating from a decision block to explain different decision paths.
The app allows you to add the labels to other connectors too, but this is not a common practice.
