A scale for 0 to 1 is appearing next to Y - Axis. How to disable it.

ChartJS 421 version. There is a scale for 0 to 1 next to y axis. I cannot disable it. How to disable it.

@viji545 can you share the chart config? I think you have added a linear axis (with id different from 'y') but you couldn't set yAxisID property to the dataset.

const options_line = {
scales: {
xAxes: {
display:true,
type: 'time',
time:{
minUnit:'month',
},

         ticks: {
                font: {size:6 
                }    
         }
      }
      ,
        yAxes: {
          display:true,
           ticks: {
            font: {size: 6  } ,               
             maxTicksLimit: 10      
      },

        }
        },
        responsive: false,
        plugins: {
          legend: {
              display: false,
              labels: {
                  font: {size:9}
              }
          },
        tooltips: {
          backgroundColor: "rgb(255,255,255)",
          bodyFontColor: "#858796",
          titleMarginBottom: 10,
          titleFontColor: '#6e707e',
          titleFontSize: 10,
          borderColor: '#dddfeb',
          borderWidth: 1,
        }
        }

        }

Please check the config info for the line chart

You have indicated Chart.js Version 4.2.1, however your coding shows code from Chart.js Version 2+.
Try to convert that to version 4+, as this might solve your issue.

@viji545 the default axes ids are x and y and they are coming the controller. In your case, you are using xAxes and yAxes but they are not overriding the default ones.

To fix it, you can

1. rename xAxes to x and yAxes to y
2. add to the datasets the axes ids to use, for instance xAxisID: 'xAxes', yAxisID: 'yAxes',. See codepen: https://codepen.io/stockinail/pen/ZEMopbO
3. disable the default axes adding to scales : x: {display: false}, y: {display: false}, . See codepen: https://codepen.io/stockinail/pen/ZEMopbO

@Udemology apart for tooltips node that, since version 3, is called tooltip (without 's'), the rest of the config is version4 compliant. The axes ids are the same of version 2 but they are not arrays therefore xAxes and yAxes are used as ids of axes.

This is interesting. Thank you for the heads up.
