For more rich chart customization, you can set normal CSS colors or pattern fills for chart element background colors.
You can set the pattern fill for the below chart elements:
title
series
data Label
legend
chartArea
Customize: There are three properties for pattern fill:
type: Specify the pattern fill type, refer GC.Spread.Sheets.Charts.PatternType
foregroundColor: Specify the pattern fill color of lines or dots.
backgroundColor: Specify the pattern fill background color.
You can customize the pattern fill using the following code:
var spread;
window.onload = function () {
spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"), { sheetCount: 2 });
var sheet = spread.getActiveSheet();
sheet.suspendPaint();
