you have to overrride the scale, try this: (applies to chartjs v1.x)
window.onload = function(){
var ctx = document.getelementbyid("canvas").getcontext("2d");
window.myline = new chart(ctx).line(linechartdata, {
scaleoverride : true,
scalesteps : 10,
scalestepwidth : 50,
scalestartvalue : 0
});
}

yes you can set it to min
and max
range
options: {
resposive: true,
title: {
display: true
},
hover: {
mode: 'index',
intersect: true
},
scales: {
y: {
suggestedmin: 0,
suggestedmax: 500
}
}
}

since none of the suggestions above helped me with charts.js 2.1.4, i solved it by adding the value 0 to my data set array (but no extra label):
statsdata.push(0);
[...]
var mychart = new chart(ctx, {
type: 'horizontalbar',
data: {
datasets: [{
data: statsdata,
[...]

with 1.1.1, i used the following to fix the scale between 0.0 and 1.0:
var options = {
scaleoverride: true,
scalestartvalue: 0,
scalesteps: 10,
scalestepwidth: 0.1
}

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.)

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

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.

just set the value for scalestartvalue in your options.
var options = {
// ....
scalestartvalue: 0,
}
see the documentation for this here.

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,

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

as of feb 2022, this works. here is how one can change it
var options = {
scales: {
yaxes: [{
display: true,
stacked: true,
ticks: {
min: 0, // minimum value
max: 10 // maximum value
}
}]

// or //
beginatzero: true // minimum value will be 0.
