I use highcharts to display a chart in my page. It works fine, but some times data in graph is too "condensed" so I should find a way to see the graph in a greater size.
I read several posts over internet on this subject: - in general they suggest to use highslide, but i don't want to, as my page is already overlaoded by scripts -somebody tries to pop up the content in a popup, it could fit to me but I didn't succeed - the only quasi-working example which fits to me seems to be the following: (inside the options object I add this properties).
exporting: {
buttons: {
popUpBtn: {
symbol: 'square',
_titleKey: 'FullScreenButtonTitle',
x: -60,
symbolSize:18,
symbolFill: '#B5C9DF',
hoverSymbolFill: '#779ABF',
onclick: function () {
var win=window.open('','','location=0,titlebar=0,status=0,width=780,height=350');
win.focus();
var divtag = win.document.createElement("div");
divtag.id = "div1";
win.document.body.appendChild(divtag);
win.document.write('<script type="text/javascript" src="script/highcharts/js/highcharts.js"></script>\
<script type="text/javascript" src="script/highcharts/js/modules/exporting.js"></script>');
this.options.renderTo=divtag;
var chart = new Highcharts.Chart(this.options);
win.document.close();
}
},
exportButton: {
enabled: true
},
printButton: {
enabled: true
}
}
}
However it is not working, as the div tag is not inserted and all i get is this
<html>
<head>
<script type="text/javascript" src="script/highcharts/js/highcharts.js"> </script>
<script type="text/javascript" src="script/highcharts/js/modules/exporting.js"></script>
</head></html>
I can't understand the error. I know it should be something simple but I can't get out alone.
--EDIT ---
I finally understood which could be a working strategy: create a "chartpopup.html" page, and passing it the parameters needed to build the copy of the graph I visualize.
So now I have:
index.html:
chartOptions = {
series: [
{
name: 'example',
data: [83.6, 78.8, 98.5, 93.4, 106.0]
}]
//// CUT SOME CODE
exporting: {
buttons: {
popUpBtn: {
enabled:true,
symbol: 'square',
_titleKey: 'FullScreenButtonTitle',
x: -60,
symbolSize:18,
symbolFill: '#B5C9DF',
hoverSymbolFill: '#779ABF',
onclick: function () {
look this!--------> generalPurposeGlobalVar = this;
var win=window.open('./chartpopup.html','Full Size Chart','location=0,titlebar=0,status=0,width=780,height=650');
}
},
exportButton: {
enabled: true
},
printButton: {
enabled: true
}
}
}
};
this.highChart=new Highcharts.Chart(this.chartOptions);
and chartpopup.html:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Chart full Size</title>
<script type="text/javascript" src="script/jquery-1.7.1-min.js"></script>
<script type="text/javascript" src="script/highcharts/js/highcharts.js"></script>
<script type="text/javascript" src="script/highcharts/js/modules/exporting.js"> </script>
</head>
<body>
<div id="container" style="min-width: 400px; height: 650; margin: 0 auto"></div>
<script>
var chart;
$(document).ready(function() {
var mychart=window.opener.generalPurposeGlobalVar;
mychart.options.chart.renderTo= 'container';
chart = new Highcharts.Chart(mychart.options);
});
</script>
</body>
</html>
This two pages are actually working ONLY with the default graph. If I modify and re-render the graph, I'm not able to reproduce it on the popup page!
The code I use to modify the graph is basically this:
this.chartOptions.series=[{name:field.split('_').join('\n')}];
this.highChart.destroy();
this.highChart=new Highcharts.Chart(this.chartOptions);
this.highChart.xAxis[0].setCategories(_.isEmpty(mygroups) ? [] : mygroups);
this.highChart.series[0].setData([]);
this.highChart.setTitle({text: this.highChart.title.text},{text:(field.split('_').join(' ')), });
this.highChart.redraw();//
[...]
self.highChart.series[0].addPoint(result);//it's a point I calculated before
