dotnet wrapper how to add watermark

Hi

I'm doing research what i can achive with dotnet wrapper for Highcharts and so far is fantastic. But i have problem with adding
watermark to graph (also when exported). I just can't find any solutions (all are javascript specific). Is there a way to achive that in
C# code?

Thank you

Hello andraz,
Welcome to our forum and thanks for contacting us with your question!

All you have to use is Highcharts.Credits and set it properly.

Feel free to ask any further questions!

Thank you for response,

but credits does not allow to add image (as far as i know) only text (if i try to add html in text that won't be visible when user exports graph as image or other available formats). I have found some javascript examples where image is added to graph
with renderer.Image but that option renderer in wrapper does not have.

Hello andraz, sorry for the late reply.

I am attaching a URL to download a file with an example demo of rendered image as a watermark here: https://www83.zippyshare.com/v/zouC4Y9Q/file.html

Let me know if that fits your requirements.
