SciChart® the market leader in Fast WPF Charts, WPF 3D Charts, iOS Chart, Android Chart and JavaScript Chart Components

Hello,

we plan to generate reports containing SciChart charts, so we can re-use the chart components we show in our web-application. We did the same successfully in the past with SciChart for WPF.

So far I didn’t find any special support to generate high quality print output (and printing for js charts in general). Using the web-browsers print function the charts are rendered as bitmaps at screen resolution. In SciChart for WPF you provide a Vector Rendering Plugin which we used for printing (as described here https://support.scichart.com/index.php?/Knowledgebase/Article/View/17263/40).

Is there already support for high quality rendering in SciChart.js or do you have plans for it and maybe a timeline when to expect it?

I found one issue when printing from the example charts (https://demo.scichart.com/javascript-line-chart). After opening with a new browser window, on the first print the page content in the print dialog is most times empty but after reloading (F5) it is apparently always shown. I don’t know yet if this would be an issue when rendering to a PDF which we plan, but I think this should always work at the first time a page is loaded. Tested with current Chrome (88.0.4324.104) and Edge (88.0.705.56).

I wanted to attach a .png screenshot (435 KiB) but it didn’t work (a progress bar runs to 100% but then the file list is still empty tried file selection and drag&drop ). I think the issue should be understandable without a screenshot?

Update
I could add the image using the edit function.

Greetings,

Nils

Hi Nils,

Thank you for writing the question.

I tried several times printing this page https://demo.scichart.com/javascript-line-chart to PDF. In fact, I did not get any problems and the result seems to be quite good. Please look at the attached file.

Unfortunately, we do not have a support for high quality rendering in SciChart.js and do not have this task in the release plan.
However, we would really appreciate if you create a feature request for our roadmap. Please give a detailed description of the needed functionality.

Here is how: https://www.scichart.com/feedback-policy/ (Please add “For JavaScript” at the topic of the request).

Best regards,
Michael
