You can customize the points by initializing the point colors. The customization options allows to differentiate the [start], [end], [positive], [negative], and [low] points. This customization is only applicable for line, column, and area type sparklines.
//Initialize Sparkline component
var sparklineInstance = new ej.charts.Sparkline({
height: '150px',
width: '130px',
dataSource: [
{ x: 0, xval: 'AUDI', yval: 1 },
{ x: 1, xval: 'BMW', yval: 5 },
{ x: 2, xval: 'BUICK', yval: -1 },
{ x: 3, xval: 'CETROEN', yval: -6 },
{ x: 4, xval: 'CHEVROLET', yval: 0 },
{ x: 5, xval: 'FIAT', yval: 1 },
{ x: 6, xval: 'FORD', yval: -2 },
{ x: 7, xval: 'HONDA', yval: 7 },
{ x: 8, xval: 'HYUNDAI', yval: -9 },
{ x: 9, xval: 'JEEP', yval: 0 },
{ x: 10, xval: 'KIA', yval: -10 },
{ x: 11, xval: 'MAZDA', yval: 3 }
],
// Assign the dataSource values to series of sparkline 'xName and yName'
xName: 'xval', yName: 'yval',
// Assign the 'Column' as type of Sparkline
type:'Column',
// Assign the value type as "Category" to the sparkline
valueType: 'Category',
// To configure sparkline series highest y value point color.
highPointColor:'blue',
// To configure sparkline series lowest y value point color.
lowPointColor:'orange',
// To configure sparkline series first x value point color.
startPointColor:'green',
// To configure sparkline series last x value point color.
endPointColor:'green',
// To configure sparkline series negative y value point color.
negativePointColor:'red'
});
//Render initialized Sparkline

Tie point color is used to configure the win-loss series type sparkline’s y-value point color. The following code sample shows the tie point color of sparkline series.
//Initialize Sparkline component
var sparklineInstance = new ej.charts.Sparkline({
height: '150px',
width: '130px',
dataSource: [12, 15, -10, 13, 15, 6, -12, 17, 13, 0, 8, -10],
// Assign the 'WinLoss' as type of Sparkline
type:'WinLoss',
// Assign the value type as "Numeric" to the sparkline
valueType: 'Numeric',
tiePointColor:'blue'
});
//Render initialized Sparkline
sparklineInstance.appendTo("#element");<!DOCTYPE html><html lang="en"><head>
