Question

How can I remove the labels and keep the Y axis?

I don’t want remove the axis, only the labels. Basically the y axis without text or numbers

chart1.addAxis("y", {
                labels: false,
                vertical : true,
                leftBottom : true,

            });

Answer 1

can you try like this:

addAxis("y", {
                vertical: true,
                fixLower: "major",
                fixUpper: "major",
        labelFunc:function(){
          return " ";
             }
         });

Pls. Dont remove the one single space inside the quotes.
