From Function, select the function of the Response variable. For example, if you select Maximum, Minitab defines the color gradient for the wafer plot based on the maximum value
of the response variable in each rectangle.
Some options require you to enter additional values.
- Percentile
- If you select Percentile, you must enter a value in Percentile value. The value must be between 0 and 100. Minitab uses the value you
enter to define the color gradient in the wafer plot. For example, if
you enter 50, Minitab uses the 50th percentile to define the color
gradient for each rectangle of the wafer plot.
- Percent between two values
- If you select Percent between two values, you must enter numeric values in First value and Second value. The value you enter for First value must be less than or equal to the value you enter for Second value. Minitab defines the color gradient for the wafer plot based on the
percentage of observations that is between the two values.
- Percent equal to specified values
- If you select Percent equal to specified values, you must enter one or more values in Values. The values must be the same type of data as the column you entered
in Response variable. Minitab defines the color gradient for the wafer plot based on the
percentage of observations that is equal to the values that you enter.
