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].

<template>
    <div class="control_wrapper">
    <div class="spark">
        <ejs-sparkline id="sparkline" align="center" :dataSource='dataSource' xName='xDate' yName='yval' :type='type' :valueType='valueType' :height='height' :width='width'></ejs-sparkline>
    </div>
    </div>
</template>
<script>
import Vue from 'vue';
import { SparklinePlugin } from "@syncfusion/ej2-vue-charts";
Vue.use(SparklinePlugin);

export default {
  data: function() {
    return {
    height: '150px',
    width: '130px',
    // Assign the "Column" as type of the sparkline
    type:'Column',
    // Assign the "DateTime" as value type to the sparkline
    valueType: 'DateTime',
    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 },

.spark {
    width: 100%;
    height: 100%;
}
</style>

Category

You can assign category values to the sparkline by setting [valueType] to [Category].

<template>
    <div class="control_wrapper">
    <div class="spark">
        <ejs-sparkline id="sparkline" align="center" :dataSource='dataSource' xName='xval' yName='yval' :height='height' :type='type' :valueType='valueType' :width='width'></ejs-sparkline>

You can assign numeric values to the sparkline by setting the [valueType] to [Numeric].

<template>
    <div class="control_wrapper">
    <div class="spark">
        <ejs-sparkline id="sparkline" align="center" :dataSource='dataSource'  :type='type' :valueType='valueType' xName='x' yName='yval' :height='height' :width='width'></ejs-sparkline>

<style>
.spark {
    width: 100%;
    height: 100%;

</style>

Change min and max values of axis

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.

<template>
    <div class="control_wrapper">
    <div class="spark">
        <ejs-sparkline id="sparkline" align="center" :dataSource='dataSource' :type= 'type' :axisSettings='axisSettings' :valueType='valueType' xName='x' yName='yval' :height='height' :width='width'></ejs-sparkline>
    </div>
    </div>
</template>
<script>
import Vue from 'vue';
import { SparklinePlugin } from "@syncfusion/ej2-vue-charts";
Vue.use(SparklinePlugin);

export default {
  data: function() {
    return {
    height: '150px',
    width: '130px',
    axisSettings: {
        minY: 0, maxY: 150
    },
    // Assign the 'Column' as type of the sparkline
    type:'Column',
    // Assign the 'Numeric' as value type of the sparkline
    valueType: 'Numeric',
    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 }
        ]
    }
  }
}
</script>
<style>
.spark {
    width: 100%;
    height: 100%;
}
</style>

Change value of axis

You can set horizontal axis line value of the sparkline by setting [value] to the [axisSettings] property. The following code example shows this.

<template>
    <div class="control_wrapper">
    <div class="spark">
        <ejs-sparkline id="sparkline" align="center" :dataSource='dataSource' :type='type' :valueType= 'valueType' :axisSettings='axisSettings' xName='x' yName='yval' :height='height' :width='width'></ejs-sparkline>
    </div>
    </div>
</template>
<script>
import Vue from 'vue';
import { SparklinePlugin } from "@syncfusion/ej2-vue-charts";
Vue.use(SparklinePlugin);

export default {
  data: function() {
    return {
    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 }
        ],
    // Set the value to horizontal axis of sparkline
    axisSettings: {
          value: 25
    },
    // Assign the 'Column' as type of the sparkline
    type:'Column',
    // Assign the 'Numeric' as value type of the sparkline
    valueType: 'Numeric'
    }
  }
}
</script>
<style>
.spark {
    width: 100%;
    height: 100%;
}
</style>

Axis line customization

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.

<template>
    <div class="control_wrapper">
    <div class="spark">
        <ejs-sparkline id="sparkline" align="center" :dataSource='dataSource' :axisSettings='axisSettings' :valueType='valueType'  xName='x' yName='yval' :height='height' :width='width'></ejs-sparkline>
    </div>
    </div>
</template>
<script>
import Vue from 'vue';
import { SparklinePlugin } from "@syncfusion/ej2-vue-charts";
Vue.use(SparklinePlugin);

export default {
  data: function() {
    return {
    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 }
        ],
    // 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'
    }
  }
}
</script>
<style>
.spark {
    width: 100%;
    height: 100%;
