I have been working on exporting Highchart to JPEG image. I have downloaded the asp.net code for exporting.
Everything works fine, just the image exported has a blank square on the up-left corn. (sorry, I don't have enough reputation to post an image) However, the exact same code, but I change the export url to "http://export.highcharts.com/", then export to image, it looks fine.
So I am assuming nothing is wrong with my code? unless I have missed some configurations? Can anybody help thanks.
