## Line class

Encapsulates the object that represents the line format.

```javascript
class Line;
```


### Example
```javascript
const { Workbook, ChartType, LineType, ChartMarkerType, WeightType } = AsposeCells;

var workbook = new Workbook();
var cells = workbook.worksheets.get(0).cells;
cells.get("a1").putValue(2);
cells.get("a2").putValue(5);
cells.get("a3").putValue(3);
cells.get("a4").putValue(6);
cells.get("b1").putValue(4);
cells.get("b2").putValue(3);
cells.get("b3").putValue(6);
cells.get("b4").putValue(7);
var chartIndex = workbook.worksheets.get(0).charts.add(ChartType.Column, 11, 0, 27, 10);
var chart = workbook.worksheets.get(0).charts.get(chartIndex);
chart.nSeries.add("A1:B4", true);
//Applying a dotted line style on the lines of an NSeries
chart.nSeries.get(0).border.style = LineType.Dot;
//Applying a triangular marker style on the data markers of an NSeries
chart.nSeries.get(0).marker.markerStyle = ChartMarkerType.Triangle;
//Setting the weight of all lines in an NSeries to medium
chart.nSeries.get(0).border.weight = WeightType.MediumLine;
```
