## ChartPointCollection class

Represents a collection that contains all the points in one series.

```javascript
class ChartPointCollection;
```


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

//Instantiating a Workbook object
var workbook = new Workbook();
//Obtaining the reference of the first worksheet
var worksheet = workbook.worksheets.get(0);
//Adding a sample value to "A1" cell
worksheet.cells.get("A1").putValue(50);
//Adding a sample value to "A2" cell
worksheet.cells.get("A2").putValue(100);
//Adding a sample value to "A3" cell
worksheet.cells.get("A3").putValue(150);
//Adding a sample value to "B1" cell
worksheet.cells.get("B1").putValue(60);
//Adding a sample value to "B2" cell
worksheet.cells.get("B2").putValue(32);
//Adding a sample value to "B3" cell
worksheet.cells.get("B3").putValue(50);
//Adding a chart to the worksheet
var chartIndex = worksheet.charts.add(ChartType.PieExploded, 5, 0, 25, 10);
//Accessing the instance of the newly added chart
var chart = worksheet.charts.get(chartIndex);
//Adding NSeries (chart data source) to the chart ranging from "A1" cell to "B3"
chart.nSeries.add("A1:B3", true);
//Show Data Labels 
chart.nSeries.get(0).dataLabels.showValue = true;
var points = chart.nSeries.get(0).points;
var red = Color.Red;
for (var i = 0; i < points.count; i++) {
    //Get Data Point
    var point = points.get(i);
    //Set Pir Explosion
    point.explosion = 15;
    //Set Border Color
    point.border.color = red;
}

//Saving the Excel file
var uint8Array = workbook.save(SaveFormat.Xlsx);
```
