18 Apr 202324 minutes to read
You can customize axis value types and min and max values of the sparkline.
Change value type of the sparkline
You can change the sparkline value type by setting the [valueType] property to [Numeric], [Category], or [DateTime].
DateTime
You can assign date-time values to the sparkline by setting the [valueType] property to [DateTime].
//Initialize Sparkline component
var sparklineInstance = new ej.charts.Sparkline({
height: '150px',
width: '130px',
dataSource: [
{ xDate: new Date(2018, 0, 1), x: 0, yval: 4 },
{ xDate: new Date(2018, 0, 2), x: 1, yval: 4.5 },
{ xDate: new Date(2018, 0, 3), x: 2, yval: 8 },
{ xDate: new Date(2018, 0, 4), x: 3, yval: 7 },

{ xDate: new Date(2018, 0, 11), x: 8, yval: 4 },
{ xDate: new Date(2018, 0, 12), x: 9, yval: 5.5 }
],
// Assign the dataSource values to series of sparkline 'xName and yName'
xName: 'xDate', yName: 'yval',
// Assign the 'Column' as type of Sparkline
type:'Column',
// Assign the value type as "DateTime" to the sparkline
valueType: 'DateTime'
});

You can change the min and max values of x-axis by setting the [minX] and [maxX] values to the [axisSettings] property. You can also change the min and max values of y-axis by setting the [minY] and [maxY] values to the [axisSettings] property.
//Initialize Sparkline component
var sparklineInstance = new ej.charts.Sparkline({
height: '150px',
width: '130px',
dataSource: [
{ x: 0, yval: 50 },
{ x: 1, yval: 30 },

],
// Assign the dataSource values to series of sparkline 'xName and yName'
xName: 'x', yName: 'yval',
// Set min and max values to the y axis of sparkline
axisSettings: {
minY: 0, maxY: 150
},
// Assign the 'Column' as type of Sparkline
type:'Column',
// Assign the value type as 'Numeric' to the sparkline

You can set horizontal axis line value of the sparkline by setting [value] to the [axisSettings] property. The following code example shows this.
//Initialize Sparkline component
var sparklineInstance = new ej.charts.Sparkline({
height: '150px',
width: '130px',
dataSource: [
{ x: 0, yval: 50 },
{ x: 1, yval: 30 },

{ x: 4, yval: 50 },
{ x: 5, yval: 40 },
{ x: 6, yval: 20 },
{ x: 7, yval: 10 },
{ x: 8, yval: 30 },
{ x: 9, yval: 10 },
{ x: 10, yval: 40 }
],
// Assign the dataSource values to series of sparkline 'xName and yName'
xName: 'x', yName: 'yval',
// Set the value to horizontal axis of sparkline
axisSettings: {
value: 25
},
// Assign the 'Column' as type of Sparkline
type:'Column',
// Assign the value type as 'Numeric' to the sparkline
valueType: 'Numeric'
});
//Render initialized Sparkline

Axis of the sparkline can be collapsed using the [visible] property in [lineSettings]; this is not applicable for win-loss. You can customize the [color], [width], [opacity], and [dashArray] of axis line.
//Initialize Sparkline component
var sparklineInstance = new ej.charts.Sparkline({
height: '150px',
width: '130px',
dataSource: [
{ x: 0, yval: 50 },
{ x: 1, yval: 30 },
{ x: 2, yval: 20 },
{ x: 3, yval: 30 },
{ x: 4, yval: 50 },
{ x: 5, yval: 40 },
{ x: 6, yval: 20 },
{ x: 7, yval: 10 },
{ x: 8, yval: 30 },
{ x: 9, yval: 10 },
{ x: 10, yval: 40 }
],
// Assign the dataSource values to series of sparkline 'xName and yName'
xName: 'x', yName: 'yval',
// Set the value to horizontal axis
axisSettings: {
// To configure axis line settings
lineSettings: {
visible: true,
color: "#ff14ae",
dashArray:5
}
},
// Assign the value type as 'Numeric' to the sparkline
valueType: 'Numeric'
});
