I'm looking to export a customized chart simliar to the post here Export Highcharts to PDF (using javascript and local server - no internet connection) that references http://fiddle.jshell.net/leighking2/dct9tfvn/. This has the exact functionality that I'm looking for, however I have my chart/data in a sepearte file/controller. Does anyone know how I could take the concept from the post I listed above, but incorporate it into my controller?
Didn't want to include my whole index.html file but here are the two charts from it.
<div id="allCharts" class="col-md-6" >
<button class="export_all" >export all</button>
<highchart id="chart1" config="chartConfig" class="span9 myChart" ></highchart>
<hr>
<highchart id="chart2" config="chartConfig2" class="span9 myChart" ></highchart>
</div>'use strict';
var myapp = angular.module('myapp', ["highcharts-ng"]);
myapp.controller('myctrl', function ($scope) {
$scope.chartConfig = {
options: {
chart: {
type: 'line'
},
xAxis: {
categories: ['Year 1', 'Year 2', 'Year 3', 'Year 4', 'Year 5'],
title: {
text: null
}
},
plotOptions: {
line: {
events: {
legendItemClick: function () {
return false;
}
}
}, allowPointSelect: false,
series: {
stacking: ''
}
}
},
series: [{ "name": "Purchase Costs", data: $scope.purchaseChartData }, { "name": "Rental Costs", data: $scope.rentalChartData }],
title: {
text: 'Rental and Purchase Costs'
},
credits: {
enabled: true
},
loading: false,
size: {}
};
$scope.chartConfig2 = {
options: {
chart: {
type: 'column'
},
xAxis: {
categories: ['Year 1', 'Year 2', 'Year 3', 'Year 4', 'Year 5'],
title: {
text: null
}
},
plotOptions: {
column: {
events: {
legendItemClick: function () {
return false;
}
}
}, allowPointSelect: false,
series: {
stacking: ''
}
}
},
exporting:{
allowHTML:true
},
series: [{ "name": "Annual Savings", data: $scope.savingsChartData }],
title: {
useHTML:false,
text: 'Savings Compounded Annually'
},
credits: {
enabled: true
},
loading: false,
size: {}
};
$scope.reflow = function () {
$scope.$broadcast('highchartsng.reflow');
};
});Question Update
Thanks Vaelyr! I now have the print button working; however I only have it adding text. I'm just having trouble linking my chart to the imageData. For now I just have the script within my html page until I get this working.
Attaching the charts to the imageData (via a loop) isn't working for me. I have class="myCharts" attached to both of my charts, but no luck. Now I'm just bacially trying to add my charts to the imageData.
<div id="allCharts" class="col-md-6" >
<button class="exportAll" onClick="printPDF()" id="export_btn">export all</button>
<highchart id="chart1" config="chartConfig" class="span9 myChart" ></highchart>
<hr>
<highchart id="chart2" config="chartConfig2" class="span9 myChart" ></highchart>
function printPDF() {
var doc = new jsPDF();
// chart height defined here so each chart can be palced
// in a different position
var chartHeight = 80;
// All units are in the set measurement for the document
// This can be changed to "pt" (points), "mm" (Default), "cm", "in"
doc.setFontSize(40);
doc.text(35, 25, "My Exported Charts");
//loop through each chart
$('.myChart').each(function (index) {
var imageData = $(this).highcharts().createCanvas();
// add image to doc, if you have lots of charts,
// you will need to check if you have gone bigger
// than a page and do doc.addPage() before adding
// another image.
/**
* addImage(imagedata, type, x, y, width, height)
*/
doc.addImage(imageData, 'JPEG', 45, (index * chartHeight) + 40, 120, chartHeight);
//add.addImage();
});
//save with name
doc.save('demo.pdf');
};
