/**
* This class can be used to modify radial gradient steps, changing visual
* properties like lightness, brightness, opacity of each set.
*
* It can also set offsets for each gradient step.
*
* E.g. if I want to fill a columns in a column series to be a solid fill from
* top to 80% of height, then gradually fades out, I can use the following
* gradient modifier as a `fillModifier`:
*
* ```TypeScript
* let fillModifier = new am4core.LinearGradientModifier();
* fillModifier.opacities = [1, 1, 0];
* fillModifier.offsets = [0, 0.8, 1];
* columnSeries.columns.template.fillModifier = fillModifier;
* ```
* ```JavaScript
* var fillModifier = new am4core.LinearGradientModifier();
* fillModifier.opacities = [1, 1, 0];
* fillModifier.offsets = [0, 0.8, 1];
* columnSeries.columns.template.fillModifier = fillModifier;
* ```
* ```JSON
