I've searched through all similar questions but I couldn't find a solution.

The Pie chart I've developed looks like below picture and I want to remove that empty space and force the chart to strech itself inside its container.

The config:

{
  grid: {
    left: 0,
    top: 0,
    right: 0,
    bottom: 0
  },
  radius: '100%',
}

CSS applied to:

width: 100%; // It doesn't matter I apply pixel width or percentage, empty space remains
height: 420px;
