Export (Vue)

Saving charts as images for inclusion in other documents is a common requirement. Some browsers support this as a context menu option, but not all.

The FlexChart's saveImageToFile method makes this really easy.

This example uses Vue.

<template> <div class="container-fluid"> <div class="form-group"> <p> Save as: <button class="btn btn-default" v-on:click="exportChart('png')">PNG</button> <button class="btn btn-default" v-on:click="exportChart('jpeg')">JPEG</button> <button class="btn btn-default" v-on:click="exportChart('svg')">SVG</button> </p> <wj-flex-chart header="Phase II Test Results" chartType="Scatter" :initialized="chartInitialized"> <wj-flex-chart-series name="Experiment 1" :itemsSource="data1" bindingX="x" binding="y"></wj-flex-chart-series> <wj-flex-chart-series name="Experiment 2" :itemsSource="data2" bindingX="x" binding="y"></wj-flex-chart-series> <wj-flex-chart-series name="Experiment 3" :itemsSource="data3" bindingX="x" binding="y"></wj-flex-chart-series> <wj-flex-chart-axis wjProperty="axisY" :axisLine="true"></wj-flex-chart-axis> </wj-flex-chart> </div> </div> </template> <script> import "@grapecity/wijmo.styles/wijmo.css"; import 'bootstrap.css'; import Vue from 'vue'; import '@grapecity/wijmo.vue2.core'; import '@grapecity/wijmo.vue2.chart'; import { getData } from './data'; import '@grapecity/wijmo.chart.render'; let App = Vue.extend({ name: 'app', data: function () { return { data1: getData(50, 0, 3), data2: getData(40, 100, 12), data3: getData(30, -100, 24) } }, methods: { chartInitialized: function(flex) { this.theChart = flex; }, exportChart(type) { this.theChart.saveImageToFile('FlexChart.' + type); } } }) new Vue({ render: h => h(App) }).$mount('#app'); </script> <style> body { margin-bottom: 24px; } .wj-flexchart { height: 300px; margin: 10px 0; background: white; } label { margin-right: 3px; } </style>
