}
}
}
</script>Opposed Position
To place an axis opposite to its original position, set the opposedPosition property to true.
<template>
<div>
<ejs-bulletchart id="bulletChart"
:dataSource="data"
valueField="value"
targetField="target"
:minimum="minimum"
:maximum="maximum"
:interval="interval"

return {
data: [{ value: 270, target: 250 }],
minimum: 0, maximum: 300, interval: 50
}
}
}
</script>Category Label
The Bullet Chart supports X-axis label by specifying the property from the data source to the categoryField. It helps to understand the input data in a more efficient way.
<template>
<div>
<ejs-bulletchart id="bulletChart"
:dataSource="data"
valueField="value"
targetField="target"
:minimum="minimum"
:maximum="maximum"
:interval="interval"
title="Revenue"
categoryField="category"

</e-bullet-range-collection>
</ejs-bulletchart>
</div>
</template>
<script>
import Vue from 'vue';
import { BulletChartPlugin } from '@syncfusion/ej2-vue-charts';
Vue.use(BulletChartPlugin);
export default {
data () {
return {
data: [{ value: 270, target: 250, category: "Product A" }],
minimum: 0, maximum: 300, interval: 50
}
}
}
</script>Category Label Customization
The label color, opacity, font size, font family, font weight, and font style can be customized by using the categoryLabelStyle setting for category and the labelStyle setting for axis label. The useRangeColor property specifies the color of the axis label and represents the color from the corresponding range colors.

<div>
<ejs-bulletchart id="bulletChart"
:dataSource="data"
valueField="value"
targetField="target"
:minimum="minimum"
:maximum="maximum"
:interval="interval"
