Guides
Guides are reference elements that help users arrange chart symbols in the ExpressFlowChart control precisely. The term “guides” includes alignment guides and size arrows.
Alignment Guides
Alignment guides are dashed lines that help users center chart symbols relative to each other and align their edges.
These guides are particularly useful when the “Snap To Grid” mode is disabled.
Size Arrows
The control displays size arrows to show that the chart symbol you are currently customizing and existing chart symbol(s) have the same height and/or width.
