Highcharts does not work with wicked_pdf

问题:

I'm trying to generate a PDF report using the Wicked_pdf gem and Highcharts. I've already tried to set animation, enableMouseTracking and shadow false. But when wkhtmltopdf tries to generated the PDF files I got an error.

I really don't not what to do, because when I do the same procedure for an HTML, Highcharts renders perfectly.

I fixed it by setting this options:

plotOptions:
  line:
    animation: false
    enableMouseTracking: false
    shadow: false

Also, don't forget to include JQuery and inline your styles and scripts

Try setting this:

series: { 'enableMouseTracking: false, shadow: false, animation: false' : nil}

This solution worked for me. I have a pdf view and a html view and implemented solution has:

<more highchart options>
...
plotOptions: {
                  line: {
                    marker: {
                      enabled: false
                    },
                    dashStyle: 'ShortDash'
                  },
                  series: { #{request.format == 'pdf' ? 'enableMouseTracking: false, shadow: false, animation: false' : nil} }
                },
...
<more highchart options>

Try debugging in the QtWeb browser.

You may find that your javascript contains unsupported syntax or keywords, which results in the issue as described.

The Qt WebKit rendering engine that wkhtmltopdf was using doesn't support ES2015, so you might have a simple solution like me, which was to replace keywords like let and const.
