History Graph Control – Mouse Dragging
You can change the size of the displayed graph by using your mouse.
You can choose to zoom bidirectionally, horizontally, or vertically.
2D Graph 2D and 3D graphs are useful tools for off-line validation of a fuzzy
system. Assume that the project deals with crisp inputs and outputs,
which is the case in most control applications. The inference realized
by the designed fuzzy system generates static input-output mapping.
2D graphs and 3D mesh plots are graphical representations of the
mapping.
When the 2D(3D) Graph is opened and the related project is manually
simulated, the system behavior is traced in yellow. To trace the system
behavior for another simulated input, the 2D(3D) graph must be
regenerated.
When you click the Tools\2D Graph main menu command, the 2D
Graph Properties dialog (see 2D Graph Properties Dialog) appears
and you can specify the 2D graph properties.
• General group box – Specify the general properties of the 2D
graph.

IMPORTANT
Dynamic components such as input ports with filters and PID
controllers, resulting in a dynamic fuzzy system, give 2D and 3D
plots different meaning and use.
