## FillFormat class

Encapsulates the object that represents fill formatting for a shape.

```javascript
class FillFormat;
```


### Example
```javascript
const { Workbook, ChartType, Color, GradientStyleType } = require("aspose.cells.node");

var excel = new Workbook();
var charts = excel.worksheets.get(0).charts;
//Create a chart
var chart = charts.get(charts.add(ChartType.Column, 1, 1, 10, 10));
chart.nSeries.add("A1:C5", true);

//Filling the area of the 2nd NSeries with a gradient
chart.nSeries.get(1).area.fillFormat.setOneColorGradient(Color.Lime, 1, GradientStyleType.Horizontal, 1);
