为了更丰富地自定义图表，现在您可以为图表元素的背景色设置常规的CSS颜色或图案填充。
您可以为以下的图表元素设置图案填充
title
series
data Label
legend
chartArea
Customize: 图案填充有三个属性。
type: 表示图案填充类型，请参考 GC.Spread.Sheets.Charts.PatternType
foregroundColor: 表示线条或点的图案填充颜色。
backgroundColor: 表示图案填充背景色。
您可以使用以下代码自定义图案填充：

window.onload = function () {
spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"), { sheetCount: 2 });
var sheet = spread.getActiveSheet();
sheet.suspendPaint();
