@mridhulkumar,
Thanks for reporting the use-case, we will investigate it further. Meanwhile, removing maximum seems to be working fine. Also, you can use scalebreaks to collapse the unnecessary region to make it better.
axisY: {
includeZero: true,
minimum: 0,
maximum: 100,
scaleBreaks: {
autoCalculate: true
}
},
Kindly refer to this JSFiddle for the working example on the same.
