The problem is on your series label:

label: {
       field: 'name',
       display: 'rotate',
       contrast: true,
       font: '12px Arial'
     },

display: 'rotate', displays the label inside the chart in some cases and outside in others, you should use instead display: 'inside',

You can see a working example here
