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.
This class allows you to display information by drawing points on an area based on a value from the features data.
DotDensityStyle(String,Double,PointStyle)
Draw(IEnumerable<BaseShape>,GeoCanvas,Collection<SimpleCandidate>,Collection<SimpleCandidate>)
DrawCore(IEnumerable<Feature>,GeoCanvas,Collection<SimpleCandidate>,Collection<SimpleCandidate>)
You will use this property when you want to specify a point style that is not just a simple colored dot. You may want to use a bitmap or take advantage of a custom fill brush.
This property gets and sets the column name that will be used for the density value.
This value should represent a value in the FeatureSource that is numeric. It will be used in conjunction with the PointToValueRatio property to deterime how many points are drawn in the area.
If you have sparse data, one way to better fill the area is to use larger point sizes. The opposite is also true; if you have lots of data, smaller point sizes look better.
None
This property gets and sets the ratio of points to value in the data.
This property controls the ratio of points on the screen to numeric value in the data. For example, if you have a value of 100 in the data and you have the ratio set to 1, then you will get 100 points drawn. A ratio of higher than 1 will draw more points than the data value; in our example, a ratio of 2 will draw 200 points. Conversely, a ratio of less than 1 will draw fewer points than the data value; in our example, a ratio of 0.5 would draw 50 points.
