I have set the y-axis label to "align: high", that is it appears on top of the y-axis, horizontally. Now, as my title goes on two lines, I'd like to center the y-axis label. I tried it with "yaxis: { title { style { text-align: center}}}" and tried as well to put some CSS into the title. But it doesn't work.
Has anyone a tip for me? Thanks a lot!
