title: Decimals on yAxis are not being displayed, even if that same code works on highcharts jsfiddle
body: <p>I am having some issues I am really running out of ideas, my root of problem is this is what am I sending to highcharts, the json is unchanged and it is working fine</p>

  please note this decimal values on  vertical axis,
  but for some unknown reason when it comes to rendering on my application, the decimal does not apply</p>

  <p>I even tried adding for example   tickInterval: 0.25, and it DOES separate it but it still shows 1 and 1 again and 1 again, and if i put   tickInterval: 0.50, it shows 2 times less on yAxis, which implies that it DOES work but it just refuses to show decimals.</p>
  
  <p>do you have any idea what might be the problem ?
  Perhaps libraries ?
  Any guidance will help me.
  Thank you</p>
