I have implemented a bar chart in react.js and I want to figure out how I can scroll in x-axis when the values are more and more. In below chart I have some search values that user do in a day. Until now I have 100+ days and I think my problem will be bigger until we reach the end of the year when I will have more values in x-axis.
My code for the chart and the options are below.
const options = {
responsive: true,
plugins: {
title: {
display: true,
},
},
};
const dataForSearchBins = {
labels,
datasets: [
{
label: "Number of searches",
data: searchBins?.map((item) => item.value),
backgroundColor: "lightBlue",
},
],
};
<Stack>
<Text style={{ textAlign: "center" }}>{`Number of clicks per ${binSize.toLowerCase()}`}</Text>
<Bar options={options} data={data} />
<Box mb={6} />
</Stack>
You can use chartjs-plugin-zoom for this.
import zoomPlugin from 'chartjs-plugin-zoom';
import { Chart as ChartJS} from 'chart.js';
ChartJS.register(zoomPlugin);
After registering zoom plugin, modify the options object.
const options = {
responsive: true,
plugins: {
title: {
display: true,
},
zoom: {
pan: {
enabled: true,
mode: 'x'
},
zoom: {
pinch: {
enabled: true // Enable pinch zooming
},
wheel: {
enabled: true // Enable wheel zooming
},
mode: 'x',
}
}
},
};

As the title says, i want to switch the tooltip header with the tootlip body text.
for me it makes no sense why the standard config is this way around...
i know i can create a custom tootlip but thats not my favorite way to do it.
the code im using currently
var options = {
series: [{
name: 'Series',
data: [v0, v1, v2, v3, v4]
}],
colors: ['#3979bd', '#c1a748', '#69b761', '#69b761', '#d54c4c'],
chart: {
type: 'bar',
height: 200
},
plotOptions: {
bar: {
distributed: true,
borderRadius: 0,
horizontal: true,
}
},
tooltip: {
enabled: true,
},
dataLabels: {
enabled: true,
},
xaxis: {
categories: ['open', 'planned', 'done', 'done cloud', 'stopped'],
}
};
var chart = new ApexCharts(document.querySelector("#overview_apex_sc4stats"), options);
chart.render();
and heres a image what i want
I'm using the library chartJs to display the data that i get from my MySQL database.
In the fucntion below, AddValuesToNavigatorChart takes the browsers data and the percentage data and displays them on the pie chart.
What i need to know, is how to add '%' in my labels ?
I found few answer with getContent('2d').. using the old way, but it's not working.
This is the function :
function AddValuesToNavigatorChart(browsers, percentage) {
checkNavigatorChart()
const data = {
labels: browsers,
datasets: [{
data: percentage,
backgroundColor: [
'rgb(192,192,192)',
'rgb(255,0,0)',
'rgb(0,0,0)',
'rgb(105,105,105)'
],
hoverOffset: 4
}]
};
const config = {
tooltips: {
enabled: false
},
type: 'pie',
data: data,
plugins: [ChartDataLabels],
options: {
showTooltips: false,
plugins: {
datalabels: {
color: 'rgb(255,255,255)',
borderWidth: '2',
align: 'top'
},
legend: {
position: 'bottom',
align: 'center',
labels: {
boxWidth: 12,
padding: 15,
usePointStyle: true,
pointStyle: 'circle'
}
},
title: {
text: 'Navigator Chart',
display: true,
color: 'rgb(0,0,0)',
position: 'top'
}
}
}
};
const NavigatorChart = new Chart(
document.getElementById('NavigatorChart'),
config
);
}
Please provide the version of chartjs that you are using.
Did you mean you want to show the % in the label of the tooltip?
For version v3.8.0, here is a working code I have just made, Link
As in option, you can edit the label of tooltip as you want:
options: {
plugins: {
tooltip: {
callbacks: {
label: (tooltipItem) => {
//tooltipItem is for the slice of the pie you are hovering now
return ' ' + tooltipItem.parsed + '%';
},
}
}
}
}
I have chart which show 3 types of label
I want to keep two of them and want to hide one Invoice Income Report. How can I hide that one label? I am using chart.js v2
var myChart = new Chart(ctx, {
type: 'bar',
data: {
labels: labels,
datasets: [{
label: 'Invoice Income Report',
data: bar_chart_data,
backgroundColor: colors,
borderWidth: 1
}, {
label: 'Below Average',
backgroundColor: ['rgba(255, 99, 132, 1)']
}, {
label: 'Above Average',
backgroundColor: ['rgba(11, 156, 49, 1)']
}]
},
options: {
scales: {
y: {
beginAtZero: true
}
},
}
});
You can simply make display false.
const options = {
responsive: true,
plugins: {
legend: {
position: 'top' as const,
display: false,
},
title: {
display: false,
text: 'Chart.js Line Chart',
},
},
};
To hide the labels on version 4.2.1 of chart.js use this:
// Example chart.
const chart = new Chart(id, {
type: 'bar', // Chart type.
data: data, // Your data.
options: {
// Add plugins to options.
plugins: {
legend: {
display: false // This hides all text in the legend and also the labels.
}
}
// add your scales or other options.
}
});
For more info use the doc: https://www.chartjs.org/docs/latest/configuration/legend.html
In chart.js, You can hide the labels using legend attribute. Add the following code in options of chart.js
legend: {
display: false
}
According to your code, after adding legend the options will be .....
options: {
scales: {
y: {
beginAtZero: true
}
},
legend: {
display: false
}
}
Add legend option to options configuration, set display to false:
, options: {
scales: {
y: {
beginAtZero: true
}
},
legend: {
display: false
}
}

I spent a day figuring this out but was unavailable to find a solution. Please if anyone can help.
So I was making a cryptocurrency tracker in React. I managed to create a table displaying several currencies and also a column where I render Apexchart for various currencies based on the JSON data that's already saved with me in a javascript file i.e I'm not making any call to API to get the data. I already have static data with me. I just rendered the static data in the form of a table.
Now the problem is with the loading time of the page. As I need to render apexcharts for all the currencies(I'm displaying 100 in total), displaying them slows down the user experience.
To improve the user experience I want to add a placeholder text "loading..." and when the apexchart is done loading only then I want to display the chart.
Below is my Graph component that's responsible for loading my apexchart.
import Chart from 'react-apexcharts';
import { ChartData } from '../data/ChartData';
class Graph extends Component {
state = {
options: {
stroke: {
width: 1.7,
},
grid: {
show: false,
},
datalabels: {
enabled: false,
},
tooltip: {
enabled: false,
},
chart: {
animations: {
enabled: false,
},
toolbar: {
show: false,
},
zoom: {
enabled: false,
},
},
yaxis: {
show: false,
labels: {
formatter: function () {
return '';
},
},
},
xaxis: {
labels: {
formatter: function () {
return '';
},
},
tooltip: {
enabled: false,
},
},
},
series: [
{
name: 'USD',
data: ChartData[this.props.idx].data,
},
],
};
render() {
return (
<div className="graph">
<div className="row">
<div className="mixed-chart">
<Chart
options={this.state.options}
series={this.state.series}
type="line"
width="200px"
height="100px"
/>
</div>
</div>
</div>
);
}
}
export default Graph;
![As you can see I have my Apexchart plotted. Now as it takes time to load the chart I want to add a placeholder text "loading" and when the chart loading completes I want to display the chart giving a better user experience]Screenshot
You just need to add the object nodata to the existing options object. The following is the object definition:
noData: {
text: "Loading...",
align: 'center',
verticalAlign: 'middle',
offsetX: 0,
offsetY: 0,
style: {
color: "#000000",
fontSize: '14px',
fontFamily: "Helvetica"
}
}
Refer to it in the documentation on below link.

I've been creating charts on my company's website with data that is populated from a csv file. I need to add two additional y axes on the right side of the chart. I tried doing so by following Highchart's instructions, but my data is coming from a CSV file and I can't manage to get the two additional axes to connect to the data. Meaning, the other two splines look flat compared to the one that is actually plotting to it's y axis.
Below is the chart's JS file. The CSV file is 4 columns, which from left to right are Date, Overall, VIX, GSPC
Thank you in advance!
function basi_overall_chart() {
//var to catch any issues while getting data
var jqxhr_basi_overall = $.get('../../datafiles/basi/company_BASI_Overall_VIXSP.csv', function (data) {
