Chart node's x-axis labels not showing up

I have a NodeRED dashboard which is a regular line chart. Now the chart get's all the data and graph the 2 lines as I would expect but I tried to replace the x-axis(default output : time) with real time 'footage'. Not sure what I do wrong here but I'm getting some wrong outputs for the x-axis. Note : I have calculated the anticipated x-axis(footage) and outputting it with "node.warn()" and I'm seeing the correct numbers there.

My code :

let topic = msg.topic;

    var leftArrayPoint = msg.payload.readResults[2].v;
    var rightArrayPoint = msg.payload.readResults[3].v;
    
    var xnew = ((((leftArrayPoint+rightArrayPoint)/2)*0.49)*4.54)/12;


    var left = {topic:"camberIN", "x":xnew, payload : msg.payload.readResults[0].v  };
    var min = {topic:"min", "x":xnew, payload : 0.005 };

    var right = {topic:"camberOUT", "x":xnew, payload : msg.payload.readResults[1].v };
    var max = {topic:"max", "x":xnew, payload : 0.04 };
    
    node.warn(leftArrayPoint);
    node.warn(rightArrayPoint);
    node.warn(xnew);

return [[left,right,min,max]];

This is my whole node :
