Alter lineThickness on mouseover?

    With a data.mouseover defined like so the initial console log correctly gives the initial lineThickness value and then subsequent mouseovers give the value I set but lineThickness is not altered in chart.

    Would I have to re-render to see it?

     data: [
    			type: "line",
    			mouseover: function(e){
    				e.chart.axisX[0].lineThickness = 5;


    After changing the value, you’ll need to re-render the chart to observe the changes. You can also use set method to change different properties of the chart. Please, take a look at this jsFiddle.
