How to set Highcharts chart maximum yAxis value
Alternatively one can use the setExtremes method also,
yAxis.setExtremes(0, 100);
Or if only one value is needed to be set, just leave other as null
yAxis.setExtremes(null, 100);
Taking help from above answer link mentioned in the above answer sets the max value with option
yAxis: { max: 100 },
On similar line min value can be set.So if you want to set min-max value then
yAxis: { min: 0, max: 100},
If you are using HighRoller php library for integration if Highchart graphs then you just need to set the option
$series->yAxis->min=0;$series->yAxis->max=100;
