## Floor class

Encapsulates the object that represents the floor of a 3-D chart.

```javascript
class Floor extends Area;
```


### Example
```javascript
const { License, Workbook, ChartType, Color, GradientPresetType, GradientStyleType, SaveFormat } = AsposeCells;

//Instantiate the License class
var license = new License();
license.setLicense(data);

//Instantiate the workbook object
var workbook = new Workbook();
//Get cells collection
var cells = workbook.worksheets.get(0).cells;
//Put values in cells
cells.get("A1").putValue(1);
cells.get("A2").putValue(2);
cells.get("A3").putValue(3);

//get charts colletion
var charts = workbook.worksheets.get(0).charts;
//add a new chart 
var index = charts.add(ChartType.Column3DStacked, 5, 0, 15, 5);
//get the newly added chart
var chart = charts.get(index);
//set charts nseries
chart.nSeries.add("A1:A3", true);
//Show data labels
chart.nSeries.get(0).dataLabels.showValue = true;

//Get chart's floor
var floor = chart.floor;
//set floor's border as red
floor.border.color = new Color("red");
//set fill format
floor.fillFormat.setPresetColorGradient(GradientPresetType.CalmWater, GradientStyleType.DiagonalDown, 2);

//save the file
var uint8Array = workbook.save(SaveFormat.Excel97To2003);
```
