Visualizaçõesmake horizontal graph with percentage :react js
I trying to make a horizontal chart with react-chartjs i want each data to show the percentage
import React, { Component } from "react";
import { HorizontalBar } from "react-chartjs-2";
export default class Button extends Component {
render() {
const dataHorBar = {
labels: ["January", "February", "March", "April", "May", "June", "July"],
datasets: [
{
label: "My First dataset",
backgroundColor: "#EC932F",
borderColor: "rgba(255,99,132,1)",
borderWidth: 1,
hoverBackgroundColor: "rgba(255,99,132,0.4)",
hoverBorderColor: "rgba(255,99,132,1)",
data: [65, 59, 80, 81, 56, 55, 40]
}
]
};
return (
<div>
<HorizontalBar data={dataHorBar} />
</div>
);
}
}

In order to use the feature for having rounded rectangles, you need to update to the v3 of chartjs, therefore, the following code will be working only on this version. But you can adapt it to a previous version, you will just not be able to change the border radius of the rectangle.
You can use the datalabels plugin, in order to display custom text in your chart, and format the label like this:
options: {
plugins: {
datalabels: {
formatter: value => value + " %", // Add the percentage after the value
align: "end",
anchor: "end",
clip: true,
}
}
}
For the shapes, you can use the option borderRadius, to have rounded edges. You can find more information here, but in the end, you just have to specify a value for the borderRadius, in each dataset:
datasets: [
{
label: "My First dataset",
backgroundColor: "#EC932F",
borderColor: "rgba(255,99,132,1)",
borderWidth: 1,
hoverBackgroundColor: "rgba(255,99,132,0.4)",
hoverBorderColor: "rgba(255,99,132,1)",
data: [65, 59, 80, 81, 56, 55, 40],
borderRadius: 50, // Give a number
}
]
Finally, for removing the grid lines, you can use this snippet, and pass those options to your chart
options: {
scales: {
x: {
grid: {
display: false // Hide x grid
}
},
y: {
grid: {
display: false // Hide y grid
}
}
}
};
That's it for the ground principle. Here is a live working example, if you really wants to see how to implement it.
