title: Highstock: label the y-axis Maximum
body: <p>Im using highstock to show some measurement values. i set minimum/maximum values for the y-values to enclose the bandwith of the data.</p>
  
  <p>My problem at the moment: i need the top label (maximum) of the y-Axis on the background grid. I tried some code with tickinterval etc, but the maximum is never visible.</p>
