# Class: LogGradientStyle

[attributes](/solutions/geotoolkit/geotoolkit_js/apis/modules/geotoolkit.welllog#attributes).[LogGradientStyle](/solutions/geotoolkit/geotoolkit_js/apis/modules/geotoolkit.welllog#loggradientstyle).LogGradientStyle

Defines log gradient fill style. This fillstyle can have a color and a pattern plus data source that can be used to gradient colors.
If you need to set the gradient color based on the " Normalization Limits " please refer to setColorRange() method.
