ThinkGeo.MapSuite.WindowsPhoneCore.ClassBreak
Note: The page was created before Map Suite 10. Map Suite 10.0 organized many classes into new namespaces and assemblies as well as had a few minor breaks in compatibility. The majority of previously built code should work without modification assuming the new namespaces are added. For guidance on upgrading your existing code, please check out MapSuite 10 Upgrade Guide.
<!– Class –> This class represents a single class break.
Remarks
Class breaks are used in the ClassBreakStyle. They allow you to display data differently depending on ranges of data in the FeatureSource.
How class breaks work:
You add a number of ClassBreak classes to the ClassBreak collection. The numeric values of the breaks are important and you must place the breaks in numerical order. For example, break 0 must be added before break 100. In each ClassBreak, you specify the style you want to represent that break. Additionally, in the ColumnName property, you specify the name of the column where we will find the data used to compare the breaks. The column name must point to a column that is numeric.
When we proceed to draw the style, we look through the ClassBreaks and select the ClassBreak that is where the features column data is greater than and closest to the break value.
Example:
Feature Value = 42
ClassBreak1.Value = 0 ClassBreak2.Value = 20 ClassBreak3.Value = 40 ClassBreak4.Value = 60
In this case, the break closest to the feature value without exceeding it is ClassBreak3(40). If the feature value had been less than zero, nothing would have been drawn. If the feature value were 1000, then ClassBreak4 would draw.
If you wanted to represent a value that is less then zero, you could do that as shown in the sample below.
Feature Value = -1
ClassBreak1.Value = Double.Min ClassBreak2.Value = 0 ClassBreak3.Value = 20 ClassBreak4.Value = 40
In this example, the first class break would be used.

Public Properties
CustomStyles
This property gets a collection of custom styles used to draw the class break.
Remarks
If you set these styles, then when the data for a feature is within the current break it will use this style to draw.
