This gradient style is a new style with the concept of GradientBrush. By specifying the LowerValue and its color, as well as the UpperValue and its color, we can set the color of each feature based on a column value using linear interpolation. | This gradient style is a new style with the concept of GradientBrush.

- | This virtual method is called from the concrete public method Draw. In this method, we take the features you passed in and draw them on the canvas you provided. Each style (based on its properties) may draw each feature differently. When implementing this virtual method, consider each feature and its column data values. You can use the full power of the GeoCanvas to do the drawing. If you need column data for a feature, be sure to override the GetRequiredColumnNamesCore and add the columns you need to the collection. In many of the styles, we add properties to allow the user to specify which field they need; then, in the GetRequiredColumnNamesCore, we read that property and add it to the collection. | + | * //This virtual method is called from the concrete public method Draw.

For example, if you have a style that colors areas blue when a certain column value is over 100, then you need to be sure you include that column name. This will ensure that the column data is returned to you in the feature when it is ready to draw.
