I am implementing chartjs, when the number of col too large. It will display like this:
My question is: Is there any way to keep the label always across?
For example:
Thanks!
You can specify maxRotation (and minRotation) in the tick configuration. Be aware that Chart.js may omit labels to ensure the text does not overlap.
options: {
scales: {
xAxes: [{
ticks: {
maxRotation: 0
}
}]
}
}

So I'm trying to configure chart.js so that there is always a slight bar shown even for the lowest value. I can see there is a "minBarLength" property which the docs says to "Set this to ensure that bars have a minimum length in pixels." but I can't seem to get this working?
Here's a sandbox using the latest version of chart.js and with the use of this property as shown here:
data: {
labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
datasets: [
{
label: "# of Votes",
data: [12, 19, 3, 5, 2, 3],
minBarLength: 4,
backgroundColor: "blue"
}
]
}
However, the lowest value is still not being displayed on the graph:
I should also note that I am aware of the "beginsAtZero" property but I don't wish to use this as this can make it difficult displaying charts that have large values.
Any help would be greatly appreciated!
Simply tell your yAxes to beginAtZero by extending the options as follows:
options: {
title: {
display: true,
text: "Custom Chart Title"
},
scales: {
yAxes: [{
ticks: {
beginAtZero: true
}
}]
}
}
you probably do not have this issue anymore, but if anyone reads this.
I am using "chart.js": "3.8.0". When you set the min of the y-Axis for example to 1 you have to set the attribute "base" of the dataset to 1 as well so that minBarLength can work.
Currently my graph looks something like this
chartjs graph with x-axis labels
Looking to remove the X axis data labels yet show the time value on hover (on a data point)
Thank you!
Using Chart.js version 2. Try ticks display false in the options section
//...
options: {
scales: {
xAxes: [{
ticks: {
display: false
}
}]
}
}
//...

I am creating a chart using chart.js. I would like to remove the gridlines, but I want to keep the little pieces(drawTicks: true), marked yellow in the image below.
Is this be possible?
I have tried:
gridLines: {
display: false,
drawTicks: true
}
But that is hiding all of the gridlines.
Yes you can,
to hide the gridlines without removing the little ticks you can do this :
gridLines: {
drawOnChartArea: false
}
I have a line chart rendered with Chart.js and I display the X axis at the bottom:
xAxes: [{ type: 'linear',
position: 'bottom',
I would like to have two X axis, one at the bottom and one at the top.
I see in the documentation that position is a string, thus one value only.
Is it possible to accomplish this?
This is an old question, but I just had the same problem. Luckily the value of xAxes is an array, so you define multiple axes like this:
xAxes: [
{ position: 'top' },
{ position: 'bottom', ... other definitions here ... }
]
I'm working with Chart.js and creating line charts. I can't seem to get rid of the line above every chart coordinate. See the picture below. Which setting do I need to change to get rid of them? Thanks.

Here is what the chart variable looks like
var chart = new Chart(chartx, {
type: 'line',
data: {
labels: labels,
datasets: [{
data: data,
fill: false,
borderColor: 'rgb(0,0,0)',
borderWidth: 1,
lineTension: 0,
pointStyle: 'dash'
}]
},
options: {
responsive: true,
maintainAspectRatio: true,
animation: false,
scales: {
xAxes: [{
display: false
}],
yAxes: [{
display: false
}]
},
legend: {
display: false,
}
},
});
This is because you put pointStyle: 'dash' in your dataset attributes.
See Chart.js doc about LineChart data structure (pointStyle is at the last row of the table) :
The style of point. Options are 'circle', 'triangle', 'rect', 'rectRot', 'cross', 'crossRot', 'star', 'line', and 'dash'. If the option is an image, that image is drawn on the canvas using drawImage.
You have to choose between the different options.
Note that there is no none option.
If you want to remove the point style, you can :
Set the pointRadius attribute of your dataset to 0 (like in this fiddle).
Import an image as stated in the second part of the blockquote, which is empty (like this one).
