# Graphical Optimization Graphs¶

Also known as an overlay graph. Produces a single plot highlighting the “sweet spot” for where response criteria can be met. It is also used to show the limits of failure in a process.

The contours are plotted at the limits specified by the Criteria.

One color (bright yellow by default) defines the acceptable factor settings.

Another color (grey by default) defines the unacceptable factor settings.

If intervals are included on the criteria, then a blend of the acceptable and unacceptable colors is used to show where the interval limits are unacceptable.

The numerical optimization solutions (flags) are carried over and displayed if the graph is on the correct slice.
