I'm attempting to use wkhtmltopdf via Rotativa to convert a basic html page which uses jquery and highcharts to render a demo chart. The chart renders correctly when displayed in a browser. Can anyone tell me what I'm doing wrong? This code results in a blank PDF.
My view:
<!DOCTYPE html>

And here's my controller:
using System.Web.Mvc;
using Rotativa;
namespace Completions.MvcApplication.Controllers.Pages
{
public class ReportsController : BasePageController
{
public ActionResult Systems()
{
return new ViewAsPdf();
}
}
}
Thanks!

I had this issue and the cause was JavaScript errors. You can confirm this by running wkhtmltopdf with the --debug-javascript flag. For more detailed debugging (e.g. line numbers) you'll have to download the QtWeb browser.
Specifically in my case the two issues were that Object.values(obj) is an undefined function and $('a:not(.ignore)') is a syntax error (when jQuery 3.1.1 tried to use the selector). The fix was to use Object.keys(obj).map(function (key) { return obj[key] }) and $('a').not('.ignore').
To me it seemed to me that the graph would stop rendering midway through. So what worked for me was setting the animation off:
plotOptions: {
series: {
animation: false
}
}
This way the chart is ready once the pdf is generated.

I am looking for the options to add a hyperlink to the stock chart. So that a user can click anywhere on the chart and redirect to another page.
Not on the series, I would like to add hyperlink on the chart itself.
You need to call function on your highchart container div.You can use following function.
$("#container").on("click", function(){
window.open('http://google.com', '_blank');
// You can also use if not cross domain request
//window.location.href='http://google.com';
});
Refer this fiddle link for example
Simply make your rendering element an <a> element with a href attribute pointing to where you wish to take users (just like any other hyperlink). Just make sure that this <a> element has a display property set as block:
$(function () {
Highcharts.chart('container', {
title: {
text: 'Monthly Average Temperature',
x: -20 //center
},
subtitle: {
text: 'Source: WorldClimate.com',
x: -20
},
xAxis: {
categories: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',
'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
},
yAxis: {
title: {
text: 'Temperature (°C)'
},
plotLines: [{
value: 0,
width: 1,
color: '#808080'
}]
},
tooltip: {
valueSuffix: '°C'
},
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'middle',
borderWidth: 0
},
series: [{
name: 'Tokyo',
data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6]
}, {
name: 'New York',
data: [-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5]

}, {
name: 'London',
data: [3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8]
}]
});
});

display: block;

Note that for this example I've used Highcharts' own Basic Line Chart demo.
I have a serie name with special character that I cannot change. How I can show it? I tried legend: { useHMTL: true }, but it's not working.
My code is here:
$(function () {
$('#container').highcharts({
title: {
useHTML: true,
text: 'Monthly Average Temperature'
},
subtitle: {
useHTML: true,
text: 'Source: WorldClimate.com'

xAxis: {

'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
},
yAxis: {

},
plotLines: [{
value: 0,
width: 1
}]
},
tooltip: {
valueSuffix: '°C'
},
legend: {
title: {
text: 'City<br/><span style="font-size: 9px; color: #666; font-weight: normal">(Click to hide)</span>',
},
layout: 'vertical',
x: -10,
y: 100
},
series: [{
name: '<Tokyo>',
data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6]
},{
name: 'London',
data: [3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8]
}]
});
});

It isn't working to <Tokio> legend
Replace in name: < with <. Otherwise legend will use that name as tag (like <span> or <div>). See demo: http://jsfiddle.net/4x6susks/3/
I am using a simple linechart.
See this example: http://jsfiddle.net/w0do5vus/5/
I want to display just a partial width of the series(including the markers).
How can I achieve this? For the line I manage to hide it, but the markers are still visible.
Thanks in advance.

How can i have two threshold's ? for min,max in this graph http://jsfiddle.net/CYJAk/16/
As an example in here there's only one threshold set
http://jsfiddle.net/gh/get/jquery/1.6/highslide-software/highcharts.com/tree/master/samples/stock/demo/area/
or
instead of threshold option in highcharts, is there way i can show red spots/points when
they fall out of min:max range?
A better way to approach this problem is to add two plot lines on the chart indicating
the minimum and maximum values allowed.
Let's say you would like to apply this to the yAxis and set a minimum of 100 and a maximum of 500, you can like so:
var min = 100;
var max = 500;
yAxis: {
min: min - 100,
max: max + 100,
plotLines: [{
id: 'limit-min',
color: '#FF0000',
dashStyle: 'ShortDash',
width: 2,
value: min,
zIndex: 0
}, {
id: 'limit-max',
color: '#FF0000',
dashStyle: 'ShortDash',
width: 2,
value: max,
zIndex: 0
}]
}
The reason for adding and subtracting 100 to the max and min values is because we'd like the plot lines to be visible on the chart.
Hope that helps.
why not render a second band behind (or over) this series which contains the normal range. Then you could see easily which points fall outside that range.
Based on the answer, I created a quick code sample. I think if you have the red line for min, you can clear see which points are falling below your allowable minimum.
