Making charts at spreadsheet

 var sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
 var chart = sheet.newChart()
    .setChartType(Charts.ChartType.LINE)
    .asLineChart()
    .addRange(sheet.getRange('a1:a21'))
    .addRange(sheet.getRange('b1:b21'))
    .addRange(sheet.getRange('c1:c21'))
    .setColors(["green", "red"])
    .setBackgroundColor("black")
    .setPosition(5, 5, 0, 0)
    .setPointStyle(Charts.PointStyle.MEDIUM)
    .setOption('useFirstColumnAsDomain', true)
    .setOption('height', 280)
    .setOption('width', 480)
