The jqxChart plug-in comes with 11 color schemes, but it is also possible to set your own colors for drawing the chart series. To customize the built-in rendering of the Chart series, you need to set the ‘color’ property of each serie to a valid ‘hex’ color value.

Code example:
seriesGroups: [
{
type:
'stackedcolumn100',
columnsGapPercent: 100,
seriesGapPercent: 5,
valueAxis:
{
unitInterval: 10,
minValue: 0,
maxValue: 100,
displayValueAxis: true,
description:

'#888888' },
series: [
{ color:

'Running', displayText: 'Running' },
{ color:
"#C5845D", dataField:
'Swimming', displayText: 'Swimming' },
{ color:
"#5B339E", dataField:
'Cycling', displayText: 'Cycling' }
