[Solved]-ChartJS: How to set fixed Y axis max and min-Chart.js

for chart.js version < 3.0:

from sanjay dutt's answer:

options:{
  scales: {
    yaxes : [{
      ticks : {
        max : 1,    
        min : -1
      }
    }]
  }
}

for chart.js version >= 3.0:

due to breaking changes in version 3.x, the above mentioned answer doesn't work anymore. chart.js created a migration guide to solve the upcoming problems. the minimum and maximum values can now be configured directly to the options.scales:

options : {
    scales : {
        y : {
            min: -1,
            max: 1,
        }
    }
}

to fix min and max value for yaxes scale use the below code.

options:{
            scales: {
                yaxes : [{
                    ticks : {
                        max : 1,    
                        min : -1
                    }
                }]
            }
        }

suggestedmax will only works when incoming data is lower than suggestedmax value. suggestedmin will works only when incoming data is greater than suggestedmin value.
