ASPxCloudControl.Scale Property

Gets or sets the algorithm that normilizes item weights.

Assembly : DevExpress.Web.v25.2.dll

Declaration

C#

[DefaultValue(Scales.Logarithmic)]
public Scales Scale { get; set; }

<DefaultValue(Scales.Logarithmic)>
Public Property Scale As Scales

Property Value

Type	Default	Description
Scales	Logarithmic

A Scales enumeration value.

Available values:

Name	Description
Linear

The linear scaling is used.

| | Logarithmic |

The logarithmic scaling is used.

Remarks

If the linear distribution is used (the Scale property is set to Scales.Linear), the weighted list ranges from 1 to 70 and the ASPxCloudControl.RankCount property is set to 7 , the smallest font size is applied to items whose weight ranges from 1 to 10. The largest font size is applied to items whose weight ranges from 61 to 70, respectively.

To make a cloud more useful, it needs to be divided up into levels with a more equal distribution. To do this, set the Scale property to Scales.Logarithmic.

Example

The following sample code demonstrates how to customize the appearance of the ASPxCloudControl control.
