Hello! I have a problem with adding a chart to PDF. I want to put a chart in my Raport in PDF for a client but I haven't had any achievements in this field for several days. This is the last thing I need to do. I'm using HTML-PDF as described in Make a PDF file . Is there any way to achieve it? Th…

I prepared a working example: [html to pdf grapf ready example] There is still an error: "SyntaxError: Unexpected token S in JSON at position 0", but the PDF is generating correctly. [{"id":"e26c21c5.1443c","type":"function","z":"783f535.d2680ac","name":"contents","func":"//globals\nvar CompanyN…

Sorry, maybe I say it wrong. I need to add Chart to pdf, I don't know how to do it. Is there a simple method to do this? PS. the pdf is generating correctly but with no chart :wink:

I don't believe that node will do it: Node for node-red to render a moustache template passed into the node as msg.template. You would need something like the html-request node to get the rendered Dashboard page. Assuming your chart is on a Dashboard. The problem is that charts are rendered dyna…

@hathemi Without changing the name of the output file to include the path where it is written (remember the user running your example might be running on a Pi, windows, mac or something else) the file might not be created so your example is incomplete and it shows an error in the debug. When provid…

I have corrected the example, now you can use it with example date provided in "Contents". I have also added my attempt to add graph. [{"id":"cd687ea2.91d25","type":"HTML-PDF","z":"74c70725.489d28","name":"HTML-PDF","output":"file","x":1170,"y":2260,"wires":[["407ee87d.6a5398"]]},{"id":"407ee87d.…

[image] hathemi: but the graph exists on th pdf file ! OMG, you are right, apart from this error "Unexpected token S in JSON at position 0" that is displayed, the graph actually appears in a pdf! But can we correct the code so that this error does not occur? It will be confusing to others. …
