System requirements for Syncfusion Vue UI components
Below is the list of minimum dependencies required to use the chart component.
|-- @syncfusion/ej2-vue-charts
|-- @syncfusion/ej2-base
|-- @syncfusion/ej2-data
|-- @syncfusion/ej2-pdf-export
|-- @syncfusion/ej2-file-utils
|-- @syncfusion/ej2-compression
|-- @syncfusion/ej2-charts
|-- @syncfusion/ej2-vue-base
|-- @syncfusion/ej2-svg-baseYou can use Vue CLI to setup your vue applications.
To install Vue CLI use the following commands.
npm install -g @vue/cli
npm install -g @vue/cli-initStart a new Vue application using below Vue CLI command.
vue init webpack-simple quickstart
cd quickstart
npm installAll the available Essential JS 2 packages are published in npmjs.com registry.
To install chart component, use the following command
npm install @syncfusion/ej2-vue-charts --saveThe —save will instruct NPM to include the chart package inside of the
dependenciessection of thepackage.json.
You can register the chart component in your application by using the Vue.use().
Refer to the code example given below.
import { ChartPlugin } from '@syncfusion/ej2-vue-charts';
Vue.use(ChartPlugin);Registering
ChartPluginin vue, will register the chart component along with its required child directives globally.

The below example shows a basic Charts,<template>

In the current application, we are going to modify the above basic chart to visualize sales data for a particular year. For this application we are going to use line series, tooltip, data label, category axis and legend feature of the chart. Please find relevant feature service name and description as follows.
LineSeries - Inject this provider to use line series.Legend - Inject this provider to use legend feature.Tooltip - Inject this provider to use tooltip feature.DataLabel - Inject this provider to use datalabel feature.Category - Inject this provider to use category feature.These modules should be injected to the provide section as follows,
import Vue from "vue";
import { ChartPlugin, LineSeries } from "@syncfusion/ej2-vue-charts";
Vue.use(ChartPlugin);
export default {
provide: {
chart: [LineSeries]
}
};
</script>This section explains how to plot below JSON data to the chart.
export default {
data() {
return {
seriesData: [
{ month: 'Jan', sales: 35 }, { month: 'Feb', sales: 28 },
{ month: 'Mar', sales: 34 }, { month: 'Apr', sales: 32 },
{ month: 'May', sales: 40 }, { month: 'Jun', sales: 32 },
{ month: 'Jul', sales: 35 }, { month: 'Aug', sales: 55 },
{ month: 'Sep', sales: 38 }, { month: 'Oct', sales: 30 },
{ month: 'Nov', sales: 25 }, { month: 'Dec', sales: 32 }
]
};
}
};series property. Now map the field names month and sales in the JSON data to the xName and
yName properties of the series, then set the JSON data to dataSource property.Since the JSON contains category data, set the valueTypefor horizontal axis to Category. By default, the axis valueType is Numeric.

as a prefix and K as a suffix to each label. This can be achieved by setting the
${value}K to the labelFormat property of axis. Here, {value} act as a placeholder
for each axis label.

}
};
},
provide: {

}
};
</script>
<style>
#container{

}
</style>You can add a title using title property to the chart to provide
quick information to the user about the data plotted in the chart.

<div id="app">
<ejs-chart id="container" :title='title' :primaryXAxis='primaryXAxis' :primaryYAxis='primaryYAxis'>

};
</script>
<style>
#container{

}
</style>You can use legend for the chart by setting the visible property to true in legendSettings object and by injecting the LegendService into the @NgModule.providers.

{ month: 'Nov', sales: 25 }, { month: 'Dec', sales: 32 }
],
primaryXAxis: {
valueType: 'Category'
},
primaryYAxis:{
labelFormat: '${value}K'
},
legendSettings: {
visible: true
},
title: "Sales Analysis"
};
},
provide: {
chart: [LineSeries, Category, Legend]
}
};
</script>
<style>
#container {
height: 350px;
}
</style>You can add data labels to improve the readability of the chart.
This can be achieved by setting the visible property to true in the dataLabel object and by injecting DataLabel into the provide.

};
},
provide: {
chart: [LineSeries, Category, DataLabel, Legend]
}
};
</script>
<style>
#container {

}
</style>The tooltip is useful when you cannot display information by using the data labels
due to space constraints. You can enable tooltip by setting the enable property as true in tooltip object and by injecting TooltipService into the @NgModule.providers.
