HTML content including generated graphs

[roydekleijn]

Thank you for submitting an issue to jsPDF. Please read carefully.

Hello,

I'm able to create PDF from HTML. However my HTML also contains some generated dynamic graphs (using: @swimlane/ngx-charts)
Now I get the following error:
Error: Uncaught (in promise): TypeError: t.className.split is not a function

Is there a way to include the generated graphs as well ?

Thanks,
Roy

Is the graph rendered in a HTML Canvas?

If so, you can do the following:

<canvas id="graph"></canvas>

var canvas = document.querySelector('#graph')
var image = new Image()

image.src = canvas.toDataURL()
// returns a base64 encoded image
// data:image/png;base64,...

Ok, and what if the graphs are generated differently ? like a SVG ?

see: https://swimlane.github.io/ngx-charts/#/ngx-charts/advanced-pie-chart

This article might help with that, although I have not specifically tried it myself
