javascript – ChartJS beginAtZero, min, max doesnt work

javascript – ChartJS beginAtZero, min, max doesnt work

key is to pass options in the Chart constructor instead of part of data

new Chart(ctx, {
    type: bar,
    data: {{ chart_data|safe }},
    options: {
        scales: {
            yAxes: [{
                display: true,
                ticks: {
                    beginAtZero: true
                }
            }]
        }
    }
});

above works for me!

@Nikolas,
Here is the fiddle where the parameters you set works well.

https://jsfiddle.net/shemdani/zkb215up/2/

    var options = {
    responsive: true,
    scales: {
        yAxes: [{
            display: true,
            ticks: {
                beginAtZero: true,
                max: 100,
                min: 0
            }
        }]
    },
    title: {
        display: true,
        text: name
    },
    tooltips: {
        mode: index,
        intersect: false,
    },
    hover: {
        mode: nearest,
        intersect: true
    },

};

var data = {
        labels: [Red, Blue, Yellow, Green, Purple, Orange],
        datasets: [{
            label: # of Votes,
            data: [32, 59, 36, 25, 68, 71],
            backgroundColor: [
                rgba(255, 99, 132, 0.2),
                rgba(54, 162, 235, 0.2),
                rgba(255, 206, 86, 0.2),
                rgba(75, 192, 192, 0.2),
                rgba(153, 102, 255, 0.2),
                rgba(255, 159, 64, 0.2)
            ],
            borderColor: [
                rgba(255,99,132,1),
                rgba(54, 162, 235, 1),
                rgba(255, 206, 86, 1),
                rgba(75, 192, 192, 1),
                rgba(153, 102, 255, 1),
                rgba(255, 159, 64, 1)
            ],
            borderWidth: 1
        }]
    }

var ctx = document.getElementById(myChart);

var chartInstance = new Chart(ctx, {
    type: line,
    data: data,
    options:options
});

Please check and see what you are doing wrong. I used the basic data from charjs documentation.

Working for version 3.2.0:

  var options = {
  // plugins, responsive etc...

      scales: {
          y: {  
             min: 0
             }
          },

  //tooltips specifications...
  }

The y-axis will start at 0:
