Label margin in Radar chart

[Bram Patelski]

Hi,

Can anyone tell me how to set a margin on the axis labels? In the attachment, the top-label "Productie" is rendered too close to the outer scale-indicator.

I might just be maximizing the scale to 149, to prevent the outer number to even render, which is another request. But setting the margin should be possible, right?

I've tried to use:

grid : {
  labelMargin: 30,

But that doesn't make any difference.

Thank you
