It is possible to either remove the grid lines or have them display in a different color.
In both options.scales.xAxes
and options.scales.yAxes
you can add
gridLines: {
display: false ,
color: "#FFFFFF"
},
(obviously you do not need to assign a colour if you are not disaplying them)
var chartColors = {
red: 'rgb(255, 99, 132)',
orange: 'rgb(255, 159, 64)',
yellow: 'rgb(255, 205, 86)',
green: 'rgb(75, 192, 192)',
blue: 'rgb(54, 162, 235)',
purple: 'rgb(153, 102, 255)',
grey: 'rgb(231,233,237)'
};
var randomScalingFactor = function() {
return (Math.random() > 0.5 ? 1.0 : -1.0) * Math.round(Math.random() * 100);
}
var MONTHS = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"];
var config = {
type: 'line',
data: {
labels: ["January", "February", "March", "April", "May", "June", "July"],
datasets: [{
label: "My First dataset",
backgroundColor: chartColors.red,
borderColor: chartColors.red,
data: [
randomScalingFactor(),
randomScalingFactor(),
randomScalingFactor(),
randomScalingFactor(),
randomScalingFactor(),
randomScalingFactor(),

fill: false,
}, {

fill: false,
backgroundColor: chartColors.blue,
borderColor: chartColors.blue,
data: [
randomScalingFactor(),

}]
},
options: {

Since v3 the scales have been changed so if you want your gridlines to have a different color you will need to configure it in options.scales[scaleID].grid.color
:
var options = {
type: 'line',
data: {
labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
datasets: [{
label: '# of Votes',
data: [12, 19, 3, 5, 2, 3],
borderColor: 'pink'
},
{
label: '# of Points',
data: [7, 11, 5, 8, 3, 7],
borderColor: 'orange'
}
]
},
options: {
scales: {
y: {
grid: {
color: 'white'
}
},
x: {
grid: {
color: 'red'
}
}
}
}
}
var ctx = document.getElementById('chartJSContainer').getContext('2d');
new Chart(ctx, options);
<body>
<canvas id="chartJSContainer" width="600" height="400"></canvas>
<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/3.6.0/chart.js"></script>
</body>

Try this:
options: {
scales: {
x: {
display: true,
grid: {
display: false
},
},
y: {
display: true,
grid: {
display: false
},
}
}
}
