[Solved]-How to set Highcharts chart maximum yAxis value-Highcharts

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;

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);
