How to set max and min value for Y axis

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.


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 
    });
}

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
            }
        }]
    }
};

Edit:

They have made some changes. Currently, this is what will work

       scales: {
            x: {
                ...,
                max: value,
                min: value
            },
            y: {
                ...same as x
            }
        }
