I have tried a lot to get a Google chart look like this,
with this code,
new google.visualization.ColumnChart(document.getElementById('onlineUsers_chart')).
draw(dataTable, {
isStacked: true,
vAxes: {
0: { 'minValue': 3050 },
1: { 'minValue': 2 }
},
series: {
0: { targetAxisIndex: 0, type: "line" },
1: { targetAxisIndex: 1 },
2: { targetAxisIndex: 1 },
3: { targetAxisIndex: 1 }
},
options: {
legend: {
position: 'bottom'
},
colors: ['#3366CC', '#DC3912', '#A6A6A6', '#3366CC'],
pointSize: 3,
chartArea: {
left: 60,
top: 20,
bottom: 60,
width: "100%",
height: "1000px"
}
}
}
);
This is what I get,
I can't figure out a way to make the minimum value of first Y axis to 3050.
And the color options and legend place options are not working properly. Should I use a different chart type instead ColumnChart?
I was able to solve the issues.
Y axis values are set using the viewWindow.min option
All the Options are working when it is stated without a 'Options' attribute.
And yes I changed the chart type to ComboChart.
Here's the code
new google.visualization.ComboChart(document.getElementById('onlineUsers_chart')).
draw(dataTable, {
isStacked: true,
vAxes: {
0: { viewWindow: { min: 3050 } },
1: { viewWindow: { min: -60 }}
},
series: {
0: { targetAxisIndex: 0, type: "line" },
1: { targetAxisIndex: 1, type: "bars" },
2: { targetAxisIndex: 1, type: "bars" },
3: { targetAxisIndex: 1, type: "bars" }
},
// options: {
legend: {
position: 'bottom'
},
colors: ['#3366CC', '#DC3912', '#A6A6A6', '#3366CC'],
pointSize: 3,
chartArea: {
left: 60,
top: 20,
bottom: 60,
width: "100%",
height: "1000px"
}
//}
}
);

I want to make area chart with smooth line. and I have tried curveType : "function" and intervals : { "style" : "area", "color" : "#D49464" } but both are not working in my case here is my code -
var options = {
chartArea: { top: -10, height: '90%', width: '90%' },
height: 40,
width: 100,
legend: 'none',
curveType: 'function',
intervals: { 'style': 'area', 'color': '#D49464' },
hAxis: {
textPosition: 'none',
minValue: 0,
},
vAxis: {
minValue: 0,
textPosition: 'none',
gridlines: { count: 0 },
baselineColor: '#FFF',
},
areaOpacity: 0.1,
isStacked: true
};
I'm learning to work with Apexcharts and need to show the labels (Y axis labels an data labels) as currency (GBP) but can't seem to find the right approach. I have looked at the locale code, but really not sure how to integrate this into my chart.
I'm trying to ensure that 1000 become 1,000 etc.
Below is the chart code
<script>
var options = {
series: [
{
name: "Price in £s",
data: [1000, 2000, 2500, 3000, 4800, 6000]
}
],
chart: {
height: 350,
type: 'bar',
id: 'areachart-2',
dropShadow: {
enabled: true,
color: '#000',
top: 18,
left: 7,
blur: 10,
opacity: 0.2
},
toolbar: {
show: false
}
},
colors: ['#f6564d', '#545454'],
dataLabels: {
enabled: false,
textAnchor: 'middle',
formatter: function(val, index) {
return val.toFixed(0);
}
},
stroke: {
curve: 'straight'
},
title: {
text: '',
align: 'left'
},
grid: {
borderColor: '#f1f1f1',
row: {
colors: ['#fff', 'transparent'], // takes an array which will be repeated on columns
opacity: 0.5
},
},
markers: {
size: 100
},
xaxis: {
categories: ['01/05/22','01/06/22','01/07/22','01/08/22','01/09/22','01/10/22'],
title: {
text: 'Month'
}
},
yaxis: {
min:00,
title: {
text: 'Price in GBP',
},
},
legend: {
position: 'top',
horizontalAlign: 'right',
floating: true,
offsetY: 100,
offsetX: 100
}
};
var chart = new ApexCharts(document.querySelector("#chart"), options);
chart.render();
</script>
In yaxis add labels formatter
labels:{
formatter: (value) => {
return `${numberWithCommas(value)} GBP`;
},
},
And use this regex to add commas
function numberWithCommas(x) {
return x.toString().replace(/\B(?<!\.\d*)(?=(\d{3})+(?!\d))/g, ",");
}
Axes labels formatting can be controlled by yaxis.labels.formatter and xaxis.labels.formatter.
yaxis: {
labels: {
formatter: function (value) {
return value + "$";
}
},
},
xaxis: {
labels: {
formatter: function (value) {
return value;
}
}
}
I'm using the latest chart.js to draw a simple histogram.
The histogram is fine but I actually need the x labels to be between the borders of every bar like this histogram_right_labels, are there any methods to approach this?
I've tried offsetGridLines: true and offsetGridLines: false, but what they actually did is moving the grid lines and not the labels, unlike what I read about their actual behaviors, I think it might be a conflict in my option settings but I don't know which, any help would be appreciated.
options: {
maintainAspectRatio: false,
layout: {
padding: {
left: 10,
right: 25,
top: 25,
bottom: 0
}
},
scales: {
xAxes: [{
gridLines: {
//display: false,
drawBorder: false,
padding: 20,
offsetGridLines: true
},
ticks: {
beginAtZero: true,
}
}],
yAxes: [{
ticks: {
padding: 10,
},
gridLines: {
color: "rgb(234, 236, 244)",
zeroLineColor: "rgb(234, 236, 244)",
drawBorder: false,
borderDash: [2],
zeroLineBorderDash: [2]
}
}],
},
legend: {
labels: {

},
display: false
},
tooltips: {

titleFontColor: '#6e707e',
titleFontSize: 14,
borderColor: '#dddfeb',
borderWidth: 1,
xPadding: 15,
yPadding: 15,
displayColors: false,

},
}
You can add a second x-axis of type: 'linear' as follows.
{
type: 'linear',
ticks: {
min: 0,
max: labels.length,
stepSize: 1,
callback: (v, i) => i == 0 ? '' : labels[i - 1]
}
}
Note that I use a ticks callback method in order to provide the desired tick label at given index.
Then you should also hide the grid lines and ticks of the default x-axis.
{
gridLines: {
display: false
},
ticks: {
display: false
}
}
Please take a look at below runnable sample code and see how it works.
const labels = ['4.80', '9.60', '14.40', '19.20', '24.00', '28.80'];
new Chart(document.getElementById('myChart'), {
type: 'bar',
data: {
labels: labels,
datasets: [{
label: "My Dataset",
data: [4, 8, 5, 7, 2, 4],
backgroundColor: 'orange',
categoryPercentage: 1,
barPercentage: 1
}]
},
options: {
scales: {
yAxes: [{
ticks: {
beginAtZero: true
}
}],
xAxes: [{
gridLines: {
display: false
},
ticks: {
display: false
}
},
{
type: 'linear',
ticks: {
min: 0,
max: labels.length,
stepSize: 1,
callback: (v, i) => i == 0 ? '' : labels[i - 1]
}
}
]
}
}
});

you can use this to put the tooltips to the right. Possibilities are top, left, right and bottom
options: {
title: {
display: true,
position: 'right'
}
}
I am migrating chart.js to 3.x as per the migration guide.
https://www.chartjs.org/docs/master/getting-started/v3-migration/
I am trying to set the xAxis zeroLineColor to "#FFFFFF" and I want to have the Grid line color as "#00FFFF" but as per the chart.js migration document document scales.[x/y]Axes.zeroLine* options of axes were removed. Use scriptable scale options instead.
I am not sure how to use scriptable scale options for setting the xAxis line zero to white.
Update:
Working example:
https://jsfiddle.net/g4vq7o2b/2/
In order to obtain different colors for the grid's zero line, you could define an array of colors for the option gridLines.color.
gridLines: {
drawBorder: false,
color: ["#FFFFFF", "#00FFFF", "#00FFFF", "#00FFFF", "#00FFFF"]
}
Since gridLines.color is a scriptable options, it also accepts a function which is invoked with a context argument for each of the underlying data values as follows:
gridLines: {
drawBorder: false,
color: context => context.tick.value == 0 ? "#FFFFFF" : "#00FFFF"
}
Please take a look at below runnable code and see how it works.
new Chart(document.getElementById("myChart"), {
type: "line",
data: {
labels: ["January", "February", "March", "April", "May", "June", "July"],
datasets: [{
label: "My Dataset",
data: [2, 3, 1, 4, 2, 4, 2],
fill: false,
backgroundColor: "rgba(0, 255, 0, 0.3)",
borderColor: "rgb(0, 255, 0)"
}]
},
options: {
scales: {
y: {
min: 0,
ticks: {
stepSize: 1
},
gridLines: {
drawBorder: false,
color: context => context.tick.value == 0 ? "#FFFFFF" : "#00FFFF"
}
},
x: {
gridLines: {
drawBorder: false,
color: context => context.tick.value == 0 ? "#FFFFFF" : "#00FFFF"
}
}
}
}
});

Using chart_v3.7.0.js cartesian time axis, for me, configuring zeroline and other gridlines works, using scriptable options.
Apply property for "context.tick.value == 0" (=baseline)
like:
...
options: {
scales: {
x: {
gridLines: {
color: "#00ff00",
},
ticks: { font: { size: 30 },
maxRotation: 90,
minRotation: 90,
},
type: 'time',
time: {
/*tooltipFormat: "DD.MM hh:mm",*/
displayFormats: {
minute: 'HH:mm',
hour: 'HH:mm',
day: 'dd.MMM',
}
},
},
y: {
grid: {
color: (line) => (line.index === 0 ? 'red' : 'rgba(0, 0, 0, 0.1)') //color of lowest horizontal grid line
color: context => context.tick.value == 0 ? "#FFFFFF" : "#00FFFF", // zero-line baseline color
lineWidth: context => context.tick.value == 0 ? 3 : 1, // zero-line baseline width
},
position: 'right', // show axis on the right
title: { display: true,
rotation: 0,
text: "°C", },
},
},
I'm trying to create a "chart" where I only want to show the x-axis. Basically I'm trying to create visualization of a range (min-max) and a point that sits in between like:
I'm unable to find any resources online on how to make this, or what this type of plot is even called. If anyone could help out, that would be awesome!
This is straightforward to achieve through styling a line chart appropriately and using linear x- & y-axes with points defined via x and y coordinates.
By keeping y at 0 you can assure the points all appear in the same horizontal position.
The example below gets the visual result you want, but you'll probably want to disable tooltips for the 'fake' x-axis line via a callback:
let range = {
min: 0,
max: 100
},
pointVal = 65;
new Chart(document.getElementById("chart"), {
type: "line",
data: {
labels: ["", "", ""],
datasets: [{
pointBackgroundColor: "green",
pointRadius: 10,
pointHoverRadius: 10,
pointStyle: "rectRot",
data: [{
x: pointVal,
y: 0
}]
}, {
// this dataset becomes the 'fake' x-axis line.
pointBackgroundColor: "black",
borderColor: "black",
data: [{
x: range.min,
y: 0
},
{
x: range.max / 2,
y: 0
},
{
x: range.max,
y: 0
}
]
}]
},
options: {
legend: {
display: false
},
hover: {
mode: "point"
},
layout: {
padding: {
left: 10,
right: 10,
top: 0,
bottom: 0
}
},
scales: {
xAxes: [{
type: "linear",
display: false
}],
yAxes: [{
display: false
}]
}
}
});
