ChartArea
ChartArea class
Encapsulates the object that represents the chart area in the worksheet.
class ChartArea extends ChartFrame;
Example
const { Workbook, ChartType, Color } = require("aspose.cells.node");
//Instantiating a Workbook object
var workbook = new Workbook();
//Obtaining the reference of the first worksheet
var worksheet = workbook.getWorksheets().get(0);
//Adding a sample value to "A1" cell
worksheet.getCells().get("A1").putValue(50);
//Adding a sample value to "A2" cell
worksheet.getCells().get("A2").putValue(100);
//Adding a sample value to "A3" cell
worksheet.getCells().get("A3").putValue(150);
//Adding a sample value to "B1" cell
worksheet.getCells().get("B1").putValue(60);
//Adding a sample value to "B2" cell
worksheet.getCells().get("B2").putValue(32);
//Adding a sample value to "B3" cell
worksheet.getCells().get("B3").putValue(50);
//Adding a chart to the worksheet
var chartIndex = worksheet.getCharts().add(ChartType.Column, 5, 0, 15, 5);
//Accessing the instance of the newly added chart
var chart = worksheet.getCharts().get(chartIndex);
//Adding NSeries (chart data source) to the chart ranging from "A1" cell to "B3"
chart.getNSeries().add("A1:B3", true);
//Getting Chart Area
var chartArea = chart.getChartArea();
//Setting the foreground color of the chart area
chartArea.getArea().setForegroundColor(Color.Yellow);
//Setting Chart Area Shadow
chartArea.setShadow(true);
//Saving the Excel file
workbook.save("output/ChartsChartArea.xls");
