Plotly.js - How do I make two y-axes associated with a single x-axis?

How do I make two y-axes associated with a single x-axis? In the image we see that each y-axis has its own x-axis. I already used anchor = 'x' in the yaxis2 layout, but nothing has changed.

Below the layout used:

var layout = {
title: 'Coeficientes',
showlegend: true,
legend: {
"orientation": "h"
},
width: 800,
height: 580,
autosize: true,
margin: {
l: 50, r: 70, b: 50, t: 50, pad: 2
},
xaxis: {title: 'Ângulo [graus]'},
yaxis: {title: '[kN/(m/s)²]'},
yaxis2 = {
title: '[kN.m/(m/s)²]',
overlaying: 'y',
side: 'right'
}
}

You can try with set xaxis and yaxis value of each trace. It's works

xaxis

yaxis

var trace1 = {
x:x,
y:y1,
type:'scatter',
xaxis:'x',
yaxis:'y'
}
var trace2 = {
x:x,
y:y2,
type:'scatter',
xaxis:'x',
yaxis:'y2'
}


Example

Sometimes grid line not adjusted. it's happens when different yaxis
range is different.
So we can overcome this issue with set of same range each y-axis

yaxis

range

var Yvalues = y1.concat(y2); // Merge y values
var yMax = Math.max.apply(Math, Yvalues);
var yMin = Math.min.apply(Math, Yvalues);
var Yrange = [yMin,yMax];//Set range

var layout = {
.......
.......
yaxis: {
range:Yrange //Set range
},
yaxis2 : {
range:Yrange, //Set range
overlaying:'y' // Set overlaying value
}
}


Hello MD NASIR... Thank for your help. I inputed my traces in your code 'codepen' but didn't work. Try my traces bellow: var x = [0.0, 30.0, 45.0, 60.0, 90.0, 120.0, 135.0, 150.0, 180.0]; var y1 = [1.608, 1.3936, 0.9648, 0.60032, 0.08576, -0.71824, -1.1685, -1.5544, -2.0582]; var y2 = [0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0];
