问题
I want to dynamically added several primitive shapes like text and images into highcharts / highstock.
Please see this fiddle.
$(function () {
var chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
spacingBottom: 50
},
xAxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
},
series: [{
data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]
}]
}, function(chart) { // on complete
$("#add").click(function(){
chart.renderer.image('http://highcharts.com/demo/gfx/sun.png', 100, 100, 30, 30)
.add();
});
});
});
After click button "Add Image", there is a image will be added to chart. Unfortunately, those dynamically added elements can not be exported to images.
Is there any possible solution to fix this?
回答1:
You can use chart.exportChart() function to achieve that: http://jsfiddle.net/B6s7V/38/
The same solution as here.
$("#export").click(function () {
chart.exportChart(null, {
chart: {
events: {
load: function () {
this.renderer.image('http://highcharts.com/demo/gfx/sun.png', 100, 100, 30, 30).add();
}
}
}
});
});
回答2:
When you export a chart, the chart SVG is regenerated from the original .Chart call. If you want to add things after the chart has drawn, do it in the charts:events:load callback.
chart: {
renderTo: 'container',
spacingBottom: 50,
events: {
load: function(){
this.renderer.image('http://highcharts.com/demo/gfx/sun.png', 100, 100, 30, 30).add();
}
}
},
See updated fiddle here.
