I am using line chart from http://www.chartjs.org/
As you can see max value (130) and min value (60) for Y axis are chosen automatically , I want max value = 500 and min value=0. Is this possible?

For chart.js V2 (beta), use:
var options = {
scales: {
yAxes: [{
display: true,
ticks: {
suggestedMin: 0, // minimum will be 0, unless there is a lower value.
// OR //
beginAtZero: true // minimum value will be 0.
}
}]
}
};
See chart.js documentation on linear axes configuration for more details.

var config = {

ChartJS v2.4.0
As shown in the examples at https://github.com/jtblin/angular-chart.js on the 7th of febuary 2017 (since this seems to be subject to frequent change):
var options = {
yAxes: [{
ticks: {
min: 0,
max: 100,
stepSize: 20
}
}]
}
This will result in 5 y-axis values as such:
100
80
60
40
20
0

I wrote a js to display values from 0 to 100 in y-axis with a gap of 20.
This is my script.js
//x-axis
var vehicles = ["Trucks", "Cars", "Bikes", "Jeeps"];
//The percentage of vehicles of each type
var percentage = [41, 76, 29, 50];
var ctx = document.getElementById("barChart");
var lineChart = new Chart(ctx, {
type: 'bar',
data: {
labels: vehicles,
datasets: [{
data: percentage,
label: "Percentage of vehicles",
backgroundColor: "#3e95cd",
fill: false
}]
},
options: {
scales: {
yAxes: [{
ticks: {
beginAtZero: true,
min: 0,
max: 100,
stepSize: 20,
}
}]
}
}
});This is the graph displayed on the web.

window.onload = function(){
var ctx = document.getElementById("canvas").getContext("2d");
window.myLine = new Chart(ctx ,{
type: 'line',
data: yourData,
options: {
scales: {
yAxes: [{
ticks: {
beginAtZero:true,
min: 0,
max: 500
}
}]
}
}
});
I configure with 'options' in v2.
You should read documentation: http://www.chartjs.org/docs/#scales-linear-scale

Just set the value for scaleStartValue in your options.
var options = {
// ....
scaleStartValue: 0,
}
See the documentation for this here.

This is for Charts.js 2.0:
The reason some of these are not working is because you should declare your options when you create your chart like so:
$(function () {
var ctxLine = document.getElementById("myLineChart");
var myLineChart = new Chart(ctxLine, {
type: 'line',
data: dataLine,
options: {
scales: {
yAxes: [{
ticks: {
min: 0,
beginAtZero: true
}
}]
}
}
});
})
Documentation for this is here: http://www.chartjs.org/docs/#scales

For Chart.js v3.2.0, do this:
let options = {
scales: {
y: {
suggestedMin: 0,
suggestedMax: 69
},
x: {
suggestedMin: 0,
suggestedMax: 420
}
}
}

In my case, I used a callback in yaxis ticks, my values are in percent and when it reaches 100% it doesn't show the dot, I used this :
yAxes: [{
ticks: {
beginAtZero: true,
steps: 10,
stepValue: 5,
min: 0,
max: 100.1,
callback: function(value, index, values) {
if (value !== 100.1) {
return values[index]
}
}
}
}],
And it worked well.

There's so many conflicting answers to this, most of which had no effect for me.
I was finally able to set (or retrieve current) X-axis minimum & maximum displayed values with chart.options.scales.xAxes[0].ticks.min (even if min & max are only a subset of the data assigned to the chart.)
Using a time scale in my case, I used:
chart.options.scales.xAxes[0].ticks.min = 1590969600000; //Jun 1, 2020
chart.options.scales.xAxes[0].ticks.max = 1593561600000; //Jul 1, 2020
chart.update();
(I found no need to set the step values or beginAtZero, etc.)
