Declaration

C#

ColorScale3ConditionalFormatting AddColorScale3ConditionalFormatting(
    Range range,
    ConditionalFormattingValue minPoint,
    Color minPointColor,
    ConditionalFormattingValue midPoint,
    Color midPointColor,
    ConditionalFormattingValue maxPoint,
    Color maxPointColor
)

VB.NET

Function AddColorScale3ConditionalFormatting(
    range As Range,
    minPoint As ConditionalFormattingValue,
    minPointColor As Color,
    midPoint As ConditionalFormattingValue,
    midPointColor As Color,

    maxPointColor As Color
) As ColorScale3ConditionalFormatting

Parameters

Name	Type	Description
range	Range	A Range object that specifies a range of cells to which the conditional formatting rule is applied.
minPoint	ConditionalFormattingValue	The ConditionalFormattingValue object that defines the minimum threshold and its ConditionalFormattingValueType type.
minPointColor	Color	A Color object that defines a color representing the minimum value in the range of cells.
midPoint	ConditionalFormattingValue	The ConditionalFormattingValue object that defines the midpoint threshold and its ConditionalFormattingValueType type.
midPointColor	Color	A Color object that defines a color representing the midpoint value in the range of cells.
maxPoint	ConditionalFormattingValue	The ConditionalFormattingValue object that defines the maximum threshold and its ConditionalFormattingValueType type.
maxPointColor	Color	A Color object that defines a color representing the maximum value in the range of cells.

Returns

Type	Description
ColorScale3ConditionalFormatting	A ColorScale3ConditionalFormatting object that represents the three-color scale conditional format.

Example

This example demonstrates how to apply a three-color scale conditional formatting rule.

1. First of all, specify the minimum, midpoint and maximum thresholds of a range to which the rule will be applied. Threshold values are determined by the ConditionalFormattingValue object that can be accessed via the ConditionalFormattingCollection.CreateValue method. The type of the threshold value is specified by one of the ConditionalFormattingValueType enumeration values and can be a number, percent, formula, or percentile. Call the ConditionalFormattingCollection.CreateValue method with the ConditionalFormattingValueType.MinMax parameter to set the minimum and maximum thresholds to the lowest and highest values in a range of cells, respectively.

2. To apply a conditional formatting rule represented by the ColorScale3ConditionalFormatting object, access the collection of conditional formats from the Worksheet.ConditionalFormattings property and call the ConditionalFormattingCollection.AddColorScale3ConditionalFormatting method with the following parameters:

   • A Range object that defines a range of cells to which the rule is applied.
   • A minimum threshold specified by the ConditionalFormattingValue object.
   • A color corresponding to the minimum value in a range of cells.
   • A midpoint threshold specified by the ConditionalFormattingValue object.
   • A color corresponding to the middle value in a range of cells.
   • A maximum threshold specified by the ConditionalFormattingValue object.
   • A color corresponding to the maximum value in a range of cells.

To remove the ColorScale3ConditionalFormatting object, use the ConditionalFormattingCollection.Remove, ConditionalFormattingCollection.RemoveAt or ConditionalFormattingCollection.Clear methods.
