chart.js y axis maximum value
var options = {
scales: {
yAxes: [{
display: true,
ticks: {
beginAtZero: true, // minimum value will be 0.

};chart js x axis start at 0
For Chart.js 2.*, the option for the scale to begin at zero is listed under the configuration options of the linear scale. This is used for numerical data, which should most probably be the case for your y-axis. So, you need to use this:
options: {
scales: {
yAxes: [{
ticks: {
beginAtZero: true
}
}]
}
}
A sample line chart is also available here where the option is used for the y-axis. If your numerical data is on the x-axis, use xAxes instead of yAxes. Note that an array (and plural) is used for yAxes (or xAxes), because you may as well have multiple axeschart js y axis integer
