From Function, select the function of the Graph
variables. For example, if you select Maximum, Minitab defines the color gradient for the heatmap based on the maximum value of the Graph
variables in each rectangle. If you enter a text column in Graph
variables, you can only select Percent equal
to specified values, Number of
Nonmissing values, or Number of
Missing values.
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 heatmap. For example, if you enter 50, Minitab uses the 50th percentile to define the color gradient for each rectangle of the heatmap.
- 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 heatmap 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 Graph
variables. Minitab defines the color gradient for the heatmap based on the percentage of observations that is equal to the values that you enter.
