react I want to hide the y-axis values and tooltip in the react chart - reactjs

Question

I am using react-chart-2.
When I hover the line graph, the tooltip is displayed, but I want to hide the tooltip when I hover the line graph.
I also want to hide the numbers 0,0.1,0.2 to 1 on the left (y-axis) of the line graph.
How can I implement this to hide the y-axis of the line graph?
Also, how do I hide the tooltip in the line graph?　
　
code
import React from "react";
import { Bar } from "react-chartjs-2";
const data = {
labels: ["January", "February", "March", "April", "May", "June", "July"],
datasets: [
{
label: "Sales",
type: "line",
data: [51, 300, 40, 49, 60, 37, 40],
fill: false,
borderColor: "#555555",
backgroundColor: "#555555",
pointBorderColor: "#000000",
pointBackgroundColor: "#EC932F",
pointHoverBackgroundColor: "#EC932F",
pointHoverBorderColor: "#EC932F",
yAxisID: "y-axis-1"
},
{
type: "bar",
label: "Visitor",
data: [200, 185, 590, 621, 250, 400, 95],
fill: false,
backgroundColor: "#F7C520",
borderColor: "#F7C520",
hoverBackgroundColor: "#E6B71E",
hoverBorderColor: "#E6B71E",
yAxisID: "y-axis-1"
}
]
};
const options = {
responsive: true,
tooltips: {
mode: "label"
},
elements: {
line: {
fill: false
}
},
scales: {
xAxes: [
{
display: true,
gridLines: {
display: true
}
}
],
yAxes: [
{
type: "linear",
display: true,
position: "left",
id: "y-axis-1",
gridLines: {
display: true
}
},
{
type: "linear",
display: true,
position: "right",
id: "y-axis-2",
gridLines: {
display: false
}
}
]
}
};
class MixExample extends React.Component {
render() {
return (
<div>
<h2>Mixed data Example</h2>
<Bar data={data} options={options} />
</div>
);
}
}
export default MixExample;

react-chartjs-2 has 2 major versions relevant to this issue: v2, which has support for chart.js 2.9.4 and below, and v3, which significantly changes a lot of options and configurations, and which supports chart.js 3.0.0 and above.
The original fork of your codesandbox link uses chart.js: 2.9.4 and react-chartjs-2: 2.1.1, which differs from the sandbox link you provided, which uses chart.js: 3.5.1 and react-chartjs-2: 3.0.4. Notably, instead of structuring your options object like
scales: {
x-axes: [ /* array of axis options... */],
y-axes: [ /* array of axis options... */],
}
where each axis has an axisID property, you structure them with the axisID as the key and the rest of the original options object is the value, such as:
scales: {
"x-axis-1": {
display: true,
gridLines: {
display: false
}
},
"y-axis-1": {
type: "linear",
display: false,
position: "left"
}
}
Furthermore, the tooltip can be disabled by moving the tooltip into plugins, as the chart.js docs say that tooltip is a part of plugins:
global options for the chart tooltips is defined in Chart.defaults.plugins.tooltip
Therefore, to disable the tooltip entirely:
plugins: {
tooltip: {
enabled: false
}
}
Since you want to only disable the tooltip for a single dataset, the solutions found here may be of some use, but I haven't tried either for myself. It may also be possible to set the global default for Chart.JS tooltips to false, then enable it on a dataset-by-dataset basis, as displayed here, accessing it via react-chartjs-2's chart ref.
For that level of customization, I would highly suggest starting from the beginning with the most up-to-date version of react-chartjs-2 and the examples therein, rather than your current v2-configured starting point.
