title: Chartjs: How to create padding between ticks and scale label
body: <p>I'm using chartjs-node to create a graph, and I use a label for the Y-axis.</p>
  
  <p>My problem is that the distance between the Y-axes ticks and label is minimal and does not look good. I've gone over the docs and couldn't find anything all that useful for this scenario... There's an option under <strong>options -> scales -> yAxes -> ticks -> padding</strong> but it doesn't give the desired effect.</p>
  
  <p>Currently I have a workaround under <strong>options -> scales -> yAxes -> ticks -> callback</strong> I manually insert spaces: 
  <code>callback: (val) =&gt; `    ${val}%`</code></p>
  
  <p>This works, but obviously is not the correct usage, and I believe that if the scale is linear this approach will prohibit me from using some of the features available with a linear scale.</p>
  
  <p>Anyone knows how I can create the separation between the ticks and the label in a more elegant way?</p>
