图表区样式支持如下属性的自定义：
Background: color , transparency.
Text: font family, font size, color, transparency.
Border: color, transparency, width, dash style.
你可以通过如下方式来获取或者设置一个chart的图表区样式：
var spread;
window.onload = function () {
spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"), { sheetCount: 2 });
initSpread(spread);
initEvent(spread);
//readSetting(new GC.Spread.Sheets.CellTypes.CheckBoxList());
};
function initSpread(spread) {
var sheet = spread.getSheet(0);
sheet.suspendPaint();
var dataArray = [
["", 'Chrome', 'Firefox', 'IE', 'Safari', 'Edge', 'Opera', 'Other'],
["2014", 0.4966, 0.1801, 0.2455, 0.0470, 0.0, 0.0150, 0.0158],
["2015", 0.5689, 0.1560, 0.1652, 0.0529, 0.0158, 0.0220, 0.0192],
["2016", 0.6230, 0.1531, 0.1073, 0.0464, 0.0311, 0.0166, 0.0225],
["2017", 0.6360, 0.1304, 0.0834, 0.0589, 0.0443, 0.0223, 0.0246]
];
sheet.setArray(0, 0, dataArray);
var chart = sheet.charts.add('Chart1', GC.Spread.Sheets.Charts.ChartType.lineMarkers, 30, 120, 480, 270, "A1:D5", GC.Spread.Sheets.Charts.RowCol.columns);
