          align: 'center',
          verticalAlign: 'middle',
      }
    }
  ]
};

Current Behavior

I would like to disable the zoom out so that user cannot zoom out and see the white spaces around the treemap. for this I set min value of scaleLimit to 100, expecting that it will be always 100 and wont zoom out further. But it's not working and I am getting unexpected zoom.

Expected Behavior

Ideally It shouldn't zoom out and just zoom in till 500.

Environment

- Browser:

Any additional comments?

I set min value of scaleLimit to 100

This value is too high. Value of 1 is like 100%, so try scaleLimit: { max: 1.5, min: 0.5 } - Demo.

Still, if we set 1 in min ( considering its minimum zoom) ideally this shouldn't zoom in at all. But here it's getting zoomed in. The original issue is , if someone wants to disable the zoom in then how can they do it?

[helgasoft]

max should be 1 to disable zoom-in (not min).
