How can I hide dataset labels in Chart.js v2?

Question

I have the following code to create a graph using Chart.js v2.1.3:

var ctx = $('#gold_chart');
var goldChart = new Chart(ctx, {
    type: 'line',
    data: {
        labels: dates,
        datasets: [{
            label: 'I want to remove this Label',
            data: prices,
            pointRadius: 0,
            borderWidth: 1
        }]
    }
});

The code looks simple, but I cannot remove the label from the graph. I tried a lot of solutions I found online, but most of them use Chart.js v1.x.

How can I remove the dataset labels?

Answer 1

Just set the label and tooltip options like so

...
options: {
    legend: {
        display: false
    },
    tooltips: {
        callbacks: {
           label: function(tooltipItem) {
                  return tooltipItem.yLabel;
           }
        }
    }
}

works like charm, thanks. by the way, how to change the gradient color of the line chart? – Legitimatize

You mean, how to use a gradient as the borderColor / backgroundColor. Just create one on the context and use that when initializing - see jsfiddle.net/g9h6gtvx – Toilworn

What if I want to use it on one dataset but not on the other one – Cinemascope

It works! just one question, where did you find all these options? – Beanpole

Unfortunately, this no longer works in the latest v2.9.3. jsfiddle.net/hwtysf64 – Nobleminded

This works for me in 3.4.1, by setting options.plugins.tooltip.callbacks.label to the function. – Callida

this didn't work for me . adding the code within plugins works not in options – Yearning

Note that in Chart JS 3 it's tooltip, not tooltips. This tripped me up for a minute. – Fiedling

Answer 2

As of 2021, the namespace has changed from options.legend to options.plugins.legend. This simple code worked for me -

options: {
  plugins: {
    legend: {
      display: false
    }
  }
}

Answer 3

add:

Chart.defaults.global.legend.display = false;

in the starting of your script code;

Simple and works perfectly. I noticed the accepted answer was breaking some things. – Ogre

In React, I did this import { Chart } from "react-chartjs-2"; Chart.defaults.global.legend.display = false; – Uprear

Doesn't this disable it for all charts, in all pages where Chart is being used? – Hinterland

New Solution ChartJS v3.1.1

The above solution is correct for previous versions of chart js prior to v3.1 for v3.1.1 use the following

 ...
 options: {
  plugins:{
   legend: {
    display: false
   }
  }
 }

For those who want to remove the actual axis labels and not just the legend in 2021 (Chart.js v.3.5.1). Note: this also removes the axes.

const chartWrap = document.querySelector('.chart-wrap')
const canvas = document.createElement('canvas')

chartWrap.appendChild(canvas)
const ctx = canvas.getContext('2d')

const myChart = new Chart(ctx, {
    type: 'line',
    data: {
        labels: ['Your', 'axis', 'labels'],
        datasets: [
            {
                label: 'Your legend label',
                data: [1, 3, 2],
                backgroundColor: '#54ACEF'
            }
        ]
    },
    options: {
        maintainAspectRatio: false,
        plugins: {
            legend: false // Hide legend
        },
        scales: {
            y: {
                display: false // Hide Y axis labels
            },
            x: {
                display: false // Hide X axis labels
            }
        }   
    }
})

<div class="chart-wrap" style="width: 200px; height: 100px;"></div>

This does not remove the axis labels but the entire axes togehter with the grid – Heedful

Oh dang, you're right @LeeLenalee. I should probably rephrase. Thanks for the comment :) – Chee

Answer 6

You can also put the tooltip onto one line by removing the "title":

this.chart = new Chart(ctx, {
    type: this.props.horizontal ? 'horizontalBar' : 'bar',
    options: {
        legend: {
            display: false,
        },
        tooltips: {
            callbacks: {
                label: tooltipItem => `${tooltipItem.yLabel}: ${tooltipItem.xLabel}`, 
                title: () => null,
            }
        },
    },
});

It's just as simple as adding this:

legend: {
    display: false,
}

Or if you want you could use this other option which should also work:

Chart.defaults.global.legend.display = false;``

Scion

options: { legend: { display: false, }} It helps to write which block to put it in (this is basically the problem with the documentation) – Peary

For v3.0.0+: options: { plugins: { legend: { display: false } } } – Candelaria

new Chart('idName', {

        }

Replace options with this snippet, will fix for Vanilla JavaScript Developers

options: {
            title: {
                text: 'Hello',
                display: true
            },
            scales: {
                xAxes: [{
                    ticks: {
                        display: false
                    }
                }]
            },
            legend: {
                display: false
            }

Answer 11

for me also needed to remove x-axis and y-axis labels. for that use:

options: {
  scales: {
    x: {
      display: false, // Hide x-axis label
    },
    y: {
      display: false, // Hide y-axis label
    }
  }
}
