Hello nurikabe!
Welcome to our forum and thanks for contacting us with your question!
Highcharts support is available to all users. If you want to ask for something, you can ask your question here on this forum or on StackOverflow. Of course, you can try Highcharts for free. Also, I suggest you upgrade Highcharts to the latest version, which is Highcharts v10.1.0. We are providing support only for the latest version, so if you will have any problems with the older version, where it works differently in the new version, we will not help you.
nurikabe,
Sorry for the late reply. Sadly, Sankey charts are not supported in the export server. You can create a ticket on the export server GitHub here:https://github.com/highcharts/node-export-server/issues and you will get more information directly from developers.
Feel free to ask any further questions.
Kind regards!
nurikabe,
Actually, support for Sankey charts in Export Server is not planned yet. Please, create a ticket and you will get information directly from the developers.
Regards!
Hello nurikabe!
I am sorry for the late response, but now I have some information for you. We apologize that the release is delayed, but we are in the process of testing and fixing issues. The situation will clear within the next month and we will then try to release the new version then.
Kind regards!
